xfs: port to fs_bdev_file_open_by_path()

Route the log and rt device opens through fs_bdev_file_open_by_path() so
each external device is registered against mp->m_super, and convert the
matching releases to fs_bdev_file_release(). The data device is still
opened and released by setup_bdev_super()/kill_block_super(); when the
log lives on the data device the open resolves to the existing (dev, sb)
entry so the superblock is acted on once.
