qcacmn: Enhance the snapshot invalidation logic

Browse Source 
Enhance the snapshot invalidation by adding following conditions.

1. (FW consumed snapshot's time stamp, packet counter >= Host snapshot's
   time stamp, packet counter) || (FW consumed snapshot's time stamp,
   packet counter < Host snapshot's time stamp, packet counter).
2. (FW forwarded snapshot's time stamp, packet counter >= Host snapshot's
   time stamp, packet counter) || (FW forwarded snapshot's time stamp,
   packet counter < Host snapshot's time stamp, packet counter).
