NFS: Simplify ->decode_dirent() calling sequence
Clean up.
The pointer returned by ->decode_dirent() is no longer used as a
pointer. The only call site (xdr_decode() in fs/nfs/dir.c) simply
extracts the errno value encoded in the pointer. Replace the
returned pointer with a standard integer errno return value.
Also, pass the "server" argument as part of the nfs_entry instead of
as a separate parameter. It's faster to derive "server" in
nfs_readdir_xdr_to_array() since we already have the directory's inode
handy. "server" ought to be invariant for a set of entries in the
same directory, right?
The legacy versions of decode_dirent() don't use "server" anyway, so
it's wasted work for them to derive and pass "server" for each entry.
