Description
Older OSDs didn't have libcls_lock, and will fail lock operations; this means
virtually all rbd operations and rados lock list will fail on older/mixed clusters.
Treat "unsupported" lock failure as non-fatal. Ideally we'd use
EOPNOTSUPP, but that error code was added relatively recently (eed28daaf8927339c2ecae1b1b06c1b63678ab03 in v0.55); before that it was EIO.
Fix by treating either error as ignorable.

- Subject changed from librbd, rados: need to handle older OSDs that don't have cls_lock to librbd: need to handle older OSDs that don't have cls_lock
Actually, rados lock list should continue to fail.
