Btrfs: align offsets for btrfs_ordered_update_i_size
Some callers of btrfs_ordered_update_i_size can now pass in a NULL for the ordered extent to update against. This makes sure we properly align the offset they pass in when deciding how much to bump the on disk i_size. Signed-off-by: Chris Mason <chris.mason@oracle.com>
