Setup the initial LED state on attach and resume.
Setup the initial LED state on attach and resume.

Some of the NICs I have here power up with the LEDs blinking, which is
incorrect. The blinking should only occur when the NIC is attempting
to associate.

* On powerup, set the state to HAL_LED_INIT, which turns on the "Power" MAC
  LED but leaves the "Network" MAC LED the way it is.

* On resume, also init it to HAL_LED_INIT unless in station mode, where
  it's forced to HAL_LED_RUN. Hopefully the net80211 state machine will
  call newstate() at some point, which will refiddle the LEDs.

I've tested this on a handful of 11n and pre-11n NICs. The blinking
behaviour is slightly more sensible now.
