ipw2x00: simplify scan_event handling
* Drop unnesssary delayd_work_pending() tests.
* Unify scan_event_{now|later} by using mod_delayed_work() w/ 0 delay
for scan_event_now.
* Make ipw2200 scan_event handling match ipw2100 - use
mod_delayed_work() w/ 0 delay for immediate scanning.
Only compile tested.
