btrfs: remove unused parameter from btrfs_check_super_valid
None of the checks need to know the ro/rw status as they're all not changing the superblock. Moreover, we can access the sb flags directly if we'd need to decide by the ro/rw status. Reviewed-by: Liu Bo <bo.li.liu@oracle.com> Signed-off-by: David Sterba <dsterba@suse.com>
