bcachefs: bch2_snapshot_table_make_room()

Add a better helper for check_snapshot_exists().

create_snapids() can't be changed to use this, unfortunately, because
the transaction that creates new snapshot will also be inserting other
keys (e.g. root inode) that reference that snapshot ID, and they expect
the snapshot table to already be updated.
