NFSD: Fix NFSv4's PUTPUBFH operation
According to RFC 8881, all minor versions of NFSv4 support PUTPUBFH.
Replace the XDR decoder for PUTPUBFH with a "noop" since we no
longer want the minorversion check, and PUTPUBFH has no arguments to
decode. (Ideally nfsd4_decode_noop should really be called
nfsd4_decode_void).
PUTPUBFH should now behave just like PUTROOTFH.
