rtl8187: always set MSR_LINK_ENEDCA flag with RTL8187B
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.
