__ieee80211_key_destroy() calls synchronize_rcu() in
order to sync the tx path before destroying the key.

However, synching the tx path can be done with
synchronize_net() as well, which is usually faster
(the timing might be important for roaming scenarios).

There are a number of functions that shouldn't really
be used when modern functions that take the band are
available in cfg80211. Remove these, but for now keep
 * ieee80211_freq_to_dsss_chan and
 * ieee80211_dsss_chan_to_freq
as they're used in older drivers.

In multi-channel scenarios, the channel that we will
transmit a probe request on isn't always the current
channel (which will be NULL anyway) but will instead
be the channel that the AP is on. Pass the channel
to the ieee80211_send_probe_req() function so it can
be used in the different scenarios. The scan code
continues to pass the current channel, of course.

Even for single-channel devices it is possible that we
switch the channel temporarily (e.g. for scanning) but
while doing so process a received frame that was still
received on the old channel, so checking the current
band is racy. Use the band from status instead.

With the move to multi-channel and away from

Also break some overly long lines in the code.

Using local->_oper_channel_type in the mesh code is
completely wrong as this value is the combination

there are multiple virtual interfaces.

Use sdata->vif.bss_conf.channel_type instead as it
tracks the per-vif channel type.
