ceph: Check for err on mds request in atomic_open
The error returned by ceph_mdsc_do_request includes errors sending the
request, errors on timeout, or any errors coming from the mds. If
ceph_mdsc_do_request returns an error, the reply struct will most likely
be bogus. We need to bail out and propogate the error instead of
overwriting it.
