[PATCH 2/2] xfs: attach inode to dquot in xfs_bui_item_recover

From: Darrick J. Wong <darrick.wong@oracle.com>

In the bmap intent item recovery code, we must be careful to attach the
inode to its dquots (if quotas are enabled) so that a change in the
shape of the bmap btree doesn't cause the quota counters to be
incorrect.
