dm verity: skip verity work on I/O errors when system is shutting down
If emergency system shutdown is called, like by thermal shutdown,
dm device could be alive when the block device couldn't process
I/O requests anymore. In this status, the handling of I/O errors
by new dm I/O requests or by those already in-flight can lead to
a verity corruption state, which is misjudgment.
So, skip verity work for I/O error when system is shutting down.
