qcacmn: Add changes to log peer unmap event count

Currently host does not maintain peer map and unmap
event count, due to which its difficult to check
if host has received peer unmap events for all peer map.

To fix the issue maintain peer map and unmap count and dump
stats in case of duplicate peer map event.
