Hi,

Recently, our use-case ran into 2 bugs in case doing xfs_remove when the
disk space is in-pressure, which may cause xfs shutdown and kernel crash
in the xfs log recovery procedure. Here are 2 patches to fix the problem.

The 1st patch fixes an uninitialized variable issue.

The 2nd patch ensures the blkno in the xfs_buf is updated when doing
xfs_da3_swap_lastblock().

Thanks,
Jiachen
