Fix ToR-Agent crash for VxLan Acquire failure

Issue:
------
if VxLan Acquire for a renewed logical switch entry fails
while trying to delete and release previously allocated
VxLan ID it fails on checking for entry being active,
since this check is happening inline in Add/Change
processing where state of the entry was not yet updated
and results in assertion

Fix:
----
pass a vraiable indicating Add/Change in process to skipp
assertion check, which will otherwise will cause false
failure.
