From: Lo-Hsiang Lo <double.lo@xxxxxxxxxxx> There is a system warning message, warn_slowpath-fmt, during suspend while using supplicant join AP and enable wowl feature by IW command. It's caused by brcmf_pno_remove_request path can't find the reqid. This fix will not go to remove pno request function if there is no pno scan.
