Log message:
	Replace incomplete pvmove activation failure recovery code with a message.
	
	As it stands, the recovery code can make things worse sometimes so it's
	better to insist on a proper 'pvmove --abort' cleanup.

 Version 2.02.89 - 
 ==================================
+  Replace incomplete pvmove activation failure recovery code with a message.
   Abort if _finish_pvmove suspend_lvs fails instead of cleaning up incompletely.
   Change suspend_lvs to call vg_revert internally.
   Change vg_revert to void and remove superfluous calls after failed vg_commit.
