nfsd: dynamically skip encoded fattr bitmap in _nfsd4_verify
_nfsd4_verify currently skips 3 words from the encoded buffer begining.
With support for 3-word attr bitmaps in nfsd41, nfsd4_encode_fattr
may encode 1, 2, or 3 words, and not always 2 as it used to be, hence
we need to find out where to skip using the encoded bitmap length.
Note: This patch may be applied over pre-nfsd41 nfsd.
