qcacmn: Fix wifistats issue for WIN

For WIN, a specific raw event handler is used for handling
WMI_CTRL_PATH_STATS_EVENTID received from FW.

As a part of control path stats infrastructure, event handler
for WMI_CTRL_PATH_STATS_EVENTID is different and this results
in wifistats functionality break for WIN side.

Make changes to use WIN specific event handler.
