SUNRPC: add svcauth_map_clnt_to_svc_cred_local

Add new funtion svcauth_map_clnt_to_svc_cred_local which maps a
generic cred to a svc_cred suitable for use in nfsd.

This is needed by the localio code to map nfs client creds to nfs
server credentials.

Following from net/sunrpc/auth_unix.c:unx_marshal() it is clear that
->fsuid and ->fsgid must be used (rather than ->uid and ->gid). In
addition, these uid and gid must be translated with from_kuid_munged()
so local client uses correct uid and gid when acting as local server.

Jeff Layton noted:
This is where the magic happens. Since we're working in
kuid_t/kgid_t, we don't need to worry about further idmapping.

NFSD 6.12 Release Notes

Notable features of this release include:

- Pre-requisites for automatically determining the RPC server thread
count
- Clean-up and preparation for supporting LOCALIO, which will be
merged via the NFS client tree
- Enhancements and fixes to NFSv4.2 COPY offload
- A new Python-based tool for generating kernel SunRPC XDR encoding
and decoding functions, added as an aid for prototyping features
in protocols based on the Linux kernel's SunRPC implementation.

As always I am grateful to the NFSD contributors, reviewers,
testers, and bug reporters who participated during this cycle.

Pull nfsd updates from Chuck Lever:
"The bulk of the patches for this release are clean-ups and minor bug

There is one significant revert to mention: support for RDMA Read
operations in the server's RPC-over-RDMA transport implementation has
been fixed so it waits for Read completion in a way that avoids tying
up an nfsd thread. This prevents a possible DoS vector if an
RPC-over-RDMA client should become unresponsive during RDMA Read
operations.
