[PATCH] xfs_repair: exit with status 2 if log dirtiness is unknown

[Eric Sandeen <sandeen@xxxxxxxxxx>]

This new case is mostly like the known dirty log case; the log
is corrupt, dirtiness cannot be determined, and a mount/umount
cycle or an xfs_repair -L is required.

So exit with status 2 here as well.
