From: Hironori Shiina <shiina.hironori@xxxxxxxxx>
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.
Fixes: bf3cb3944792 ("xfs: allow single bulkstat of special inodes")
