xfs: get root inode correctly at bulkstat
The root inode number should be set to `breq->startino` for getting stat information of the root when XFS_BULK_IREQ_SPECIAL_ROOT is used. Otherwise, the inode search is started from 1 (XFS_BULK_IREQ_SPECIAL_ROOT) and the inode with the lowest number in a filesystem is returned.
