[ Upstream commit 1708e50b0145f393acbec9e319bdf0e33f765d25 ]
Refactor for clarity.
Note that op_fname is the only instance of an NFSv4 filename stored
in a struct xdr_netobj. Convert it to a u32/char * pair so that the
new nfsd4_decode_filename() helper can be used.

Convert the READ_BUF macro in nfs4xdr.c from open code to instead
use the new xdr_stream-style decoders already in use by the encode
side (and by the in-kernel NFS client implementation). Once this
conversion is done, each individual NFSv4 argument decoder can be
independently cleaned up to replace these macros with C code.

Start off the conversion to xdr_stream by de-duplicating the functions
that decode void arguments and encode void results.
