This patch adds a accessor function that allows determining if a
mapped_device is in the deleting state and then adds this check to the
target_message function. The result of this change would be that all
targets would not be allowed to process messages post a mapped device
entering the deleting state.
As previously described in the email at the archive url provided below the
target_message ioctl can result in new work / activities being started
post the mapped device entering states that new target work could cause
issues.

This patch depends on the previous patch that added dm_suspended_check due
to proximity of changes in common files.
