osmo-bts-trx: Don't attemtp to adjust MS power if fixed 

If the BSC has instructed the BTS via RSL to not autonomously perform
MS power control, we are storing this in lchan->ms_power_ctrl.fixed.

However, osmo-bts-trx would simply ignore that flag in loops.c and
continue to compute new MS power values based on measurement results.
