qlnx: Return error from qlnxr_mod_load if it fails.

Fix qlnx_rdma_register_if return ENXIO rather than -1 on error and
propagate that error to the caller in qlnxr_mod_load.

ibcore: Kernel space update based on Linux 5.7-rc1.

Overview:

This is the first stage of a RDMA stack upgrade introducing kernel
changes only based on Linux 5.7-rc1.

This patch is based on about four main areas of work:
- Update of the IB uobjects system:
- The memory holding so-called AH, CQ, PD, SRQ and UCONTEXT objects
is now managed by ibcore. This also require some changes in the
kernel verbs API. The updated verbs changes are typically about
initialize and deinitialize objects, and remove allocation and
free of memory.

- Update of the uverbs IOCTL framework:
- The parsing and handling of user-space commands has been
completely refactored to integrate with the updated IB uobjects
system.

- Various changes and updates to the generic uverbs interfaces in
device drivers including the new uAPI surface.

- The mlx5_ib_devx.c in mlx5ib and related mlx5 core changes.

Dependencies:

- The mlx4ib driver code has been updated with the minimum changes
needed.

- The mlx5ib driver code has been updated with the minimum changes
needed including DV support.

Compatibility:

- All user-space facing APIs are backwards compatible after this
change.

- All kernel-space facing RDMA APIs are backwards compatible after
this change, with exception of ib_create_ah() and ib_destroy_ah()
which takes a new flag.

- The "ib_device_ops" structure exist, but only contains the driver ID
and some structure sizes.

Differences from Linux:

- Infiniband drivers must use the INIT_IB_DEVICE_OPS() macro to set
the sizes needed for allocating various IB objects, when adding
IB device instances.

Security:

- PRIV_NET_RAW is needed to use raw ethernet transmit features.
- PRIV_DRIVER is needed to use other privileged operations.

Based on upstream Linux, Torvalds (5.7-rc1):

qlnxr: Properly initialize the Linux device structure

The driver needs to provide a LinuxKPI device structure to register
itself with the IB subsystem. It was erroneously using a copy of its
FreeBSD device structure for this purpose.

Use linux_pci_attach_device() instead, following the example of the
Chelsio iwarp driver. Also ensure that we don't leak the faked device
during detach.

Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (17 of many)

r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked).
Use it in preparation for a general review of all nodes.

This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

Mark all obvious cases as MPSAFE. All entries that haven't been marked
as MPSAFE before are by default marked as NEEDGIANT
