RTL8187B always needs MSR_LINK_ENEDCA flag to be set even when it is in
no link mode, otherwise it'll not be able to associate when this flag is
not set after the change "mac80211: fix managed mode BSSID handling".

By accident, setting BSSID of AP before association makes 8187B to
successfuly associate even when ENEDCA flag isn't set, which was the
case before the mac80211 change. But now the BSSID of AP we are trying
to associate is only available after association is successful, and
any attempt to associate without the needed flag doesn't work.
