[PATCH] dm: add uevent change event on resume

Browse Source 
Device-mapper devices are not accessible until a 'resume' ioctl has been
issued.  For userspace to find out when this happens we need to generate an
uevent for udev to take appropriate action.

As discussed at OLS we should send 'change' events for 'resume'.  We can think
of no useful purpose served by also having 'suspend' events.
