NFS: Correct size calculation for create reply length
CREATE requests return a post_op_fh3, rather than nfs_fh3. The
post_op_fh3 includes an extra word to indicate 'handle_follows'.
Without that additional word, create fails when full 64-byte
filehandles are in use.
Add NFS3_post_op_fh_sz, and correct the size calculation for
NFS3_createres_sz.
