Currently, when we are on an IBSS network with no active station, we would scan for other BSSID, even if fixed_bssid is on, due to a bug in ibss.c, where fixed_channel would be checked instead of fixed_bssid. This would trigger useless scans where scan results would not be used anyway. This patch also reverts commit 39d02a7d90602d4557ee05db2a157a4e0, which assumed that the ifibss->fixed_channel check was legitimate to disable single-channel scans. IBSS single-channel scan should now be fixed.
