rest_octets: add Serving Cell Priority Parameters

When we add an EARFCN to to the SI2quater struct we do not add Serving
Cell Priority Parameters. This essentially causes to MS to ignore the
EARFCN because it is still undefined under which conditions the MS
should change to LTE.

This is a cherry-pick from osmo-bsc.git 295c965c063a8c431507191f6aef1ef78b720685
