Darrick J. Wong fb6e584e74 xfs: make xchk_iget safer in the presence of corrupt inode btrees
commit 3f113c2739b1b068854c7ffed635c2bd790d1492 upstream.

When scrub is trying to iget an inode, ensure that it won't end up
deadlocked on a cycle in the inode btree by using an empty transaction
to store all the buffers.
