Subject: [PATCH 2/4] Ticket 49561 - MEP plugin, upon direct op failure, will
26521d
 delete twice the same managed entry
26521d
26521d
Bug Description:
26521d
	When a failure occurs during betxn_post plugin callback, the betxn_post plugins are called again.
26521d
	This is to process some kind of undo action (for example usn or dna that manage counters).
26521d
26521d
	If MEP plugin is called for a managing entry, it deletes the managed entry (that become a tombstone).
26521d
	If later an other betxn_postop fails, then MEP is called again.
26521d
	But as it does not detect the operation failure (for DEL and ADD), then it tries again
26521d
	to delete the managed entry that is already a tombstone.
26521d
26521d
Fix Description:
26521d
	The MEP betxn_post plugin callbacks (ADD and DEL) should catch the operation failure
26521d
	and return.
26521d
	It is already in place for MODRDN and MOD.
