Subject: [PATCH] NFSD, lost nfserrno() call in nfsd_setattr()


There is a regression in
	208d0ac 2014-01-07 nfsd4: break only delegations when appropriate
which deletes an nfserrno() call in nfsd_setattr() (by accident,
probably), and NFSD becomes ignoring an error from VFS.

Here is a patch to fix it.
