ceph-disk: fix mount options passed to move_mount

Commit 6cbe0f021f62b3ebd5f68fcc01a12fde6f08cff5 added a mount_options but
in certain cases it may be blank.  Fill in with the defaults, just as we

rgw: fix multi delete

Fixes: #5931
Backport: bobtail, cuttlefish

Fix a bad check, where we compare the wrong field. Instead of
comparing the ret code to 0, we compare the string value to 0
which generates implicit casting, hence the crash.
