xfs: flush outstanding buffers on log mount failure
When we fail to mount the log in xfs_mountfs(), we tear down all the infrastructure we have already allocated. However, the process of mounting the log may have progressed to the point of reading, caching and modifying buffers in memory. Hence before we can free all the infrastructure, we have to flush and remove all the buffers from memory. Problem first reported by Eric Sandeen, later a different incarnation was reported by Ben Myers.
