[iwm] if_iwm - Use chan list from ieee80211_scan_state for scan, not ic_channels.

* Limiting the channel list with "ifconfig wlan0 chanlist ..." now will
  actually set the list of channels scanned by iwm.

Tested:

* Intel 7260, STA mode, setting chanlist to 1-14 and 36-254, and indeed it does what
  it should!
