staging: r8188eu: clarify the bBusyTraffic assignment

bBusyTraffic is set only if we're not in WIFI_AP_STATE, i.e. in the else
branch. If we were not in WIFI_AP_STATE, we'd go into the if branch and
return _SUCCESS before making it to the bBusyTraffic assignment.

Move the assignment into the else branch to make this clearer.
