Well, I came up with attached diff. It works fine on iwn and wpi
too basically, wpi has a bit of an issue with the scan after resume,
I see probe resquest/response on air but the device doesn't pick
em up sometimes.. still debugging.
Anyways, I'm pretty sure that if you are doing the same for ipw/iwi
it will just work fine. The ieee80211_resume_all/suspend_all calls
will ensure that the appropriate stop/init driver functions are called.
