PCU: Fix TA adjustment

Promblem: TA provided from L1 PH-DATA-IND is a relative amount of TA adjustment to actual TA being used for given TBF. The current TA update algorithm in PCU simply applies the relative amount of TA to given TBF but does not take into account of current TA. As a result, the PCU will request wrong TA jump for given TBF if the MS is moving away from BTS more than 2 km.

Related issue: http://osmocom.org/issues/2611

Fixes: - The PCU needs increase or decrease current TA of given TBF on receiving of relative amount of TA adjustment provided by PH-DATA-IND from L1 - The PCU needs to set absolute TA of given TBF on receiving absolute TA provided by PH-RA-IND from L1.
