iwn: some initialization / RF switch state change fixes.

- Check return code from initialization path; otherwise, vap state
may be wrong after an error.
- Do not try to run iwn_stop() / iwn_init() multiple times.
- Merge iwn_radio_on/off() and move RFKILL bit check into the task.
- Try to handle possible RF switch state change in S3 state (PR 181694).
