pvscan: do nothing for device removal and event_activation=0

Browse Source 
The lvm2-pvscan service runs pvscan --cache -aay <dev> for
device addition, and pvscan --cache <dev> on device removal.
For event_activation=0, the addition does nothing.  Fix
device removal to also do nothing for event_activation=0.
Device removal was previously doing some work to process
the removal which slowed down stopping lvm2-pvscan services.
