In the continuous WiFi ON/OFF scenario, we see a lot of
"failed to parse regulatory event" prints on the console.
This is because we already would have created a regulatory
domain for the wiphy and we will discard the subsequent
events to create the same regulatory event.

Fix this error print by freeing up the regulatory resources
in WiFi OFF and create the database again in WiFi ON. The same
applies for hardware recovery as well.

Tested-on: WCN6750 hw1.0 AHB WLAN.MSL.1.0.1-00887-QCAMSLSWPLZ-1
