snapshot: create bdrv_all_find_snapshot helper
to check that snapshot is available for all loaded block drivers. The check bs != bs1 in hmp_info_snapshots is an optimization. The check for availability of this snapshot will return always true as the list of snapshots was collected from that image. The patch also ensures proper locking. Signed-off-by: Denis V.
