Fix: Change T200 of LAPDm if SAPI 0 and SAPI 3 share bandwidth on SDCCH
We use 1 second on FACCH and 2 seconds on SACCH when SMS is transfered during a call on TCH. There is no impact on bandwidth, because SAPIs use differen channels. In order to correctly transfer SMS during SDCCH, the T200 must be raised from 1 (SAPI 0) to 2 (SAPI 0 and 3), so T200 will not timeout before receiving acknowledge from BTS. This is because both SAPIs share the same ressource on SDCCH. After release of SAPI 3, T200 is lowered back to 1.
