For WCN7850 it's pointless because pktlog is not enabled: both ab->mon_reap_timer and those rings are not initialized. So remove pktlog handling in suspend/resume callbacks. And further, remove these two functions and related callee because no one is calling them. Other chips are not affected because now only WCN7850 supports suspend/resume.
