dm ioctl: introduce flag indicating uevent was generated
commit 3abf85b5b5851b5f28d3d8a920ebb844edd08352 upstream.
Set a new DM_UEVENT_GENERATED_FLAG when returning from ioctls to
indicate that a uevent was actually generated. This tells the userspace
caller that it may need to wait for the event to be processed.
