ubik: Initialize ubik_callPortal earlier

As of 7caf4143, we call ubeacon_InitServerList* before ubik_callPortal
is set, causing Rx connections to be created to port 0, causing
various problems with communicating with other sites. Initialize
ubik_callPortal to the correct value before calling any such
functions, so we create connections to the right port.
