Jonathan Brassow ba8b45cea5 dm log: fix resume failed log device 
This patch removes the possibility of having uninitialized log state if the
log device has failed.

When a mirror resumes operation, it calls 'resume' on the logging module.  If
disk based logging is being used, the log device is read to fill in the log
state.  If the log device has failed, we cannot simply return, because this
would leave the in-memory log state uninitialized.  Instead, we assume all
regions are out-of-sync and reset the log state.  Failure to do this could
result in the logging code reporting a region as in-sync, even though it
isn't; which could result in a corrupted mirror.
