mac80211: improve IBSS scanning
When IBSS is fixed to a frequency, it can still
scan to try to find the right BSSID. This makes
sense if the BSSID isn't also fixed, but it need
not scan all channels -- just one is sufficient.
Make it do that by moving the scan setup code to
ieee80211_request_internal_scan() and include
a channel variable setting.
Note that this can be further improved to start
the IBSS right away if both frequency and BSSID
are fixed.
