knfsd: various nfsd xdr cleanups

1/ decode_sattr and decode_sattr3 never return NULL, so remove
   several checks for that. ditto for xdr_decode_hyper.

2/ replace some open coded XDR_QUADLEN calls with calls to
   XDR_QUADLEN

3/ in decode_writeargs, simply an 'if' to use a single
   calculation.
   .page_len is the length of that part of the packet that did
   not fit in the first page (the head).
   So the length of the data part is the remainder of the
   head, plus page_len.

3/ other minor cleanups.
