Fixes for monitor mode:

Browse Source 
- Do not call iwn_calib_reset() for monitor mode. We do not want to query
  information and do runtime calibration while in monitor mode. Poking the
  firmware with adjustments for calibration results in firmware asserts.
  This could happened on RUN -> RUN transition only.
- Adjust blink rate for monitor mode. It's supposed to not freak out and
  turn off after a while.
- While here, remove one useless assignment of calib.state, it gets
  overwritten later in the function.
