[ Upstream commit 817644fa4525258992f17fecf4f1d6cdd2e1b731 ]

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")
