qcacmn: Fix double nbuf unmap error for Pine

When nbuf map-unmap debug is enabled and monitor vap is created on
Pine, then double nbuf unmap error is reported.
This is because in case of Pine, first monitor destination ring is
processed, then first buffer from monitor status ring is processed
to check for ppdu_id difference and then finally monitor status ring
is processed where the same buffer is unmapped again and thus resulting
in the issue.
Add fix to resolve the same.
