Vivek Goyal 48536e29e5 devicemapper: Create helpers to cancel deferred deactivation
If a device has been scheduled for deferred deactivation and container
is started again and we need to activate device again, we need to cancel
the deferred deactivation which is already scheduled on the device.

Create a method for the same.
