qcacld-3.0: Enable packet logging during driver init/re-init

Browse source 
Currently packet logging can be enabled by using the pktlogconf tool.
* Customers are not happy running the user program to collect the logs.
* There are chances of running pktlogconf between traffic.
* If packet logging is enabled after the issue has happened, we will
  miss the crucial debug info.

Hence introduce a mechanism to enable packet logging during driver load.
