qcacld-3.0: Store events in pktlog buffer when Pktlog is enabled by default in INI

Browse source 
When pktlog is enabled in INI (i.e. no iwpriv commands are issued),
store the events forwarded from firmware into the pktlog buffer.
Host will not honor any pktlog disable command if pktlog enable command
was not sent previously with WMI_PKTLOG_ENABLE_FORCE.
