NFSv4.1: Fix layoutcommit error handling
Firstly, task->tk_status will always return negative error values, so the current tests for 'NFS4ERR_DELEG_REVOKED' etc. are all being ignored. Secondly, clean up the code so that we only need to test task->tk_status once! Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com> Cc: stable@vger.kernel.org
