Just like the AP mode patch, instead of setting
the channel and then joining the mesh network,
provide the channel to join the network on to
the join_mesh() function.
Like in AP mode, you can also give the channel
to the join-mesh nl80211 command now.
Unlike AP mode, it picks a default channel if
none was given.
As libertas uses mesh mode interfaces but has
no join_mesh callback and we can't simply break
it, keep some compatibility code for that case
and configure the channel directly for it.
In the non-libertas case, where we store the
channel until join, allow setting it while the
interface is down.

If it worked (Felix says it doesn't right now), the
typical use-case for WDS interfaces would be to be
slaved to AP mode interfaces. Therefore, it isn't
necessary to set the channel on WDS interfaces. As
they don't support powersave or anything like that,
they also couldn't use a different channel anyway.

Instead of setting the channel first and then
starting the AP, let cfg80211 store the channel
and provide it as one of the AP settings.
This means that now you have to set the channel
before you can start an AP interface, but since
hostapd/wpa_supplicant always do that we're OK
with this change.
Alternatively, it's now possible to give the
channel as an attribute to the start-ap nl80211
command, overriding any preset channel.

There's no need for ieee80211_set_channel to check

ieee80211_hw_config() auto-detects it.
Additionally, it's wrong to pretend the HT config

Linus reported that due to mac80211 failing to register
the device (due to WoWLAN) his machine crashed etc. as
we double-freed the vmalloc() firmware area. His patch
to fix it was very similar to this one but I noticed
that there's another bug in the area: we complete the
completion before starting, so since we're running in
a work struct context stop() could be called while in
the middle of start() which will almost certainly lead
to issues.
Make a modification similar to his to avoid the double-
free but also move the completion to another spot so it
is only done after start() either finished or failed so
that stop() can have a consistent state.
