qcacmn: Reset Radar Log Counter on "wifi" command

Currently radar event log is cleared only during dfs_detach which happens
during wifi unload. On issuing "wifi or  wifi down" command, the logs are
not cleared. During Spoof Radar Detection, the log counter values are
spuriuos due to accumulation of phyerror events. This accumulation of
events is either due to false radar detection or logs of the previous wifi
cycle. Hence resetting the dfs radar log counters in the below cases:
1) During vap delete
2) During CC/ Regdomain change.
3) After false radar detect.
