qcacmn: Add internal stop send event

Browse Source 
In current code, EV_DOWN event in stop-progress sub state sends
stop command to FW, As EV_DOWN is generic, it is casuing multiple
stop commands to FW. To avoid, for internal transitions added new
event STOP_REQ, which send stop command to FW

EV_DOWN event is not honored in STOP state, as it is not initial state
