dm snapshot: fix oversights in optional discard support
__find_snapshots_sharing_cow() should always be used with _origins_lock
held so fix snapshot_io_hints() accordingly. Also, once a snapshot is
being merged discards must not be allowed -- otherwise incorrect or
duplicate work will be performed.
