Fix for IMPS Req sent to Firmware in connected state

Due to race condition between reception of Deauth frame from AP
and disconnect from Upper layer, driver sends IMPS Request
to firmware when firmware is in connected state.As a result
Firmware crashes.So when deauth req comes from upper layer
read the status of FW state and accordingly return the error
code so that SME does not issue IMPS request.
