qcacld-3.0: Prioritize connection req frames in pe queue

If multiple auth req comes, it added to the header of message queue
but in between mc thread could be processing some beacon frame. while
processing beacon, SAP gets assoc req and adds it to head of message
queue and will be processed first instead of auth req. After sending
of accoc rsp, mc thread will start to process queued auth req, which
is at the top of message queue which will result in deauthentication.

Reverts commit 360c5d590ec8 ("qcacld-3.0: Prioritize connection req
frames in pe queue")
