staging: wfx: fix potential dead lock between join and scan
The device disallows to start a scan request between hif_join() and
hif_set_bss_params(). The driver is not protected against that. The
worst case happens when association is aborted and hif_set_bss_params()
never happens.
mac80211 would never ask for scan during the association process. So,
this patch just aborts the association in progress when scan is
requested.
