nfsd: Fix a regression in nfsd_setattr()
[ Upstream commit 6412e44c40aaf8f1d7320b2099c5bdd6cb9126ac ]
Commit bb4d53d66e4b ("NFSD: use (un)lock_inode instead of
fh_(un)lock for file operations") broke the NFSv3 pre/post op
attributes behaviour when doing a SETATTR rpc call by stripping out
the calls to fh_fill_pre_attrs() and fh_fill_post_attrs().
