mac80211: fix ibss joining

Recent commit "mac80211: fix logic error ibss merge bssid check" fixed joining of ibss cell when static bssid is provided. In this case ifibss->bssid is set before the cell is joined and comparing that address to a bss should thus always succeed. Unfortunately this change broke the other case of joining a ibss cell without providing a static bssid where the value of ifibss->bssid is not set before the cell is joined.

Since ifibss->bssid may be set before or after joining the cell we do not learn anything by comparing it to a known bss. Remove this check.
