cfg80211 layer on DUT STA is disconnecting ongoing connection attempt after
receiving association response, because cfg80211 layer does not have valid
AP bss information. On association response event, brcmfmac communicates
the AP bss information to cfg80211 layer, but SSID seem to be empty in AP
bss information, and cfg80211 layer prints kernel warning and then
disconnects the ongoing connection attempt.

SSID is empty in SSID IE, but 'bi->SSID' contains a valid SSID, so
updating the SSID for hidden AP while informing its bss information
to cfg80211 layer.

memcpy() takes a void pointer so the cast is not needed.
