qa/tasks/ceph: ignore failure when chown ceph:ceph

[tchaikov]

we didn't have ceph:ceph user back in hammer. so ignore this error.
ceph-common will create this user in newer version. and ceph task will
take care of this, when upgrading to a newer version.

Fixes: http://tracker.ceph.com/issues/22597

being tested at http://pulpito.ceph.com/kchai-2018-01-17_15:56:05-upgrade-wip-kefu-testing-2018-01-17-0950-distro-basic-smithi/

seems like a reasonable workaround, I don't think chown would fail for any other reason, and if it did we'd find out quickly when the osd runs

changelog

• guard another "chown ceph:ceph" with try-except.

seems we are sending some command hammer cluster does not understand. and all pgs stuck in "creating" state. i will try to debug the cluster when it is still running.
