osmo-bts-trx: trx_provision_fsm: do not send *_CNF events on failure
The trx_provision_fsm currently does not check the event data (rc), causing failed operations (rc != 0) to be treated as successful confirmations. Avoid emitting *_CNF events when a command fails, ensuring that only successful operations generate confirmation events.
osmo-bts-trx: apply 'max-initial' value before POWERON
Not applying this value before powering the transceiver on results in transmission at full Tx power for a certain amount of time before the power ramping begins.
Depending on the power control interval (P_Con_INTERVAL), the MS power loop may delay the power control decision for a certain amount of SACCH block periods. In this case lchan_ms_pwr_ctrl() returns early and no logging is printed at all.
Let's always log the input values (reported level, UL measurements) early in lchan_ms_pwr_ctrl(). This is useful for debugging, and this is exactly what lchan_bs_pwr_ctrl() does.
