mwifiex: process event before command response
During extended scan, SCAN report event is always followed by command response. Sometimes It is observed that command response is processed before SCAN report which leads to a crash, because current command node is cleared while handling the response. This patch makes sure that driver's main thread gives priority to events over command responses.
