power_control: remove a logging statement and early return 

This change would allow to separate the common logic from
lchan_ms_pwr_ctrl() and re-use it for Downlink power control.

The logging statement was quite useful during early stages
of development and testing of hysteresis and filtering,
but now we can sacrifice it.
