Refactor for clarity.

Also, remove a stale comment. Commit ed94164398 ("nfsd: implement
machine credential support for some operations") added support for
SP4_MACH_CRED, so state_protect_a is no longer completely ignored.

new nfsd4_decode_filename() helper can be used.

d1c263a031 NFSD: Replace READ* macros in nfsd4_decode_fattr() 
Let's be more careful to avoid overrunning the memory that backs
the bitmap array. This requires updating the synopsis of
nfsd4_decode_fattr().

Bruce points out that a server needs to be careful to return nfs_ok
when a client presents bitmap bits the server doesn't support. This
includes bits in bitmap words the server might not yet support.

The current READ* based implementation is good about that, but that
requirement hasn't been documented.
