block: rename and alter bdrv_all_find_snapshot semantics
Currently bdrv_all_find_snapshot() will return 0 if it finds a snapshot, -1 if an error occurs, or if it fails to find a snapshot. New callers to be added want to distinguish between the error scenario and failing to find a snapshot. Rename it to bdrv_all_has_snapshot and make it return -1 on error, 0 if no snapshot is found and 1 if snapshot is found. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P.
