mlx4/OFED: replace the struct net_device with struct ifnet

Given all the code does operate on struct ifnet, the last step in this
longer series of changes now is to rename struct net_device to
struct ifnet (that is what it was defined to in the LinuxKPi code).
While mlx4 and OFED are "shared" code the decision was made years ago
to not write it based on the netdevice KPI but the native ifnet KPI
for most of it. This commit simply spells this out and with that
frees "struct netdevice" to be re-done on LinuxKPI to become a more
native/mixed implementation over time as needed by, e.g., wireless
drivers.

Infiniband clients must be attached and detached in a specific order in ibcore.

Currently the linking order of the infiniband, IB, modules decide in which

Infiniband clients must be attached and detached in a specific order in ibcore.

Currently the linking order of the infiniband, IB, modules decide in which
order the clients are attached and detached. For example one IB client may
use resources from another IB client. This can lead to a potential deadlock
at shutdown. For example if the ipoib is unregistered after the ib_multicast
client is detached, then if ipoib is using multicast addresses a deadlock may
happen, because ib_multicast will wait for all its resources to be freed before
returning from the remove method.

Fix this by using module_xxx_order() instead of module_xxx().

Fix kernel crash during fail to initialize device in ibcore.

This patch fixes the kernel crash that occurs during ib_dealloc_device()
called due to provider driver fails with an error after
ib_alloc_device() and before it can register using ib_register_device().

This crashed seen in tha lab as below which can occur with any IB device
which fails to perform its device initialization before invoking
ib_register_device().

This patch avoids touching cache and port immutable structures if device
is not yet initialized.
It also releases related memory when cache and port immutable data
structure initialization fails during register_device() state.
