atrf-path.c: moved tx init out of sample loop (breaks 230 support)

atrf-path -g ... 10 10 time is now stable at 1.92 s

- atrf-path.c (sample): commented-out init sequence needed for AT86RF230
- atrf-path.c (sample, do_sweep): set TX channel only once per +/-0.5 MHz
  pair
- atrf-path.c (sample, do_sweep): "sample" no longer needs the channel
  argument
- atrf-path.c (sample, main): do TX init only once
