Andriy Voskoboinyk 551f27f37a net80211: split scan_task() (#3) (into scan_start() and 
scan_curchan_task() functions)

(This part should fix the problem, described in
https://lists.freebsd.org/pipermail/freebsd-wireless/2016-January/006420.html)

- Rename ss_scan_task into ss_scan_start (better describes it's
current purpose)
- Utilize taskqueue_*_timeout() functions instead of current mechanism:
 * reschedule scan_curchan_task() via taskqueue_enqueue_timeout()
for every 'maxdwell' msecs (will replace infinite loop + sleeping
for 'maxdwell' period via cv_wait());
 * rerun the task immediately when an external event occurs
(instead of waking it up via cv_signal())

Also, use mtx_sleep() to wait for null frame transmission
(allows to drop conditional variable).

Tested with:
 * Intel 3945BG, STA mode;
 * RTL8188EU, STA mode.
