mac80211: Do not scan for IBSS merge with a fixed BSSID.
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.
