Rename leds external interface led_brightness_set() to led_set_brightness().
This is the second phase of the change to reduce confusion between the
leds internal and external interfaces that set brightness. With this change,
now the external interface is led_set_brightness(). The first phase renamed
the internal interface led_set_brightness() to __led_set_brightness().
There are no changes to the interface implementations.

When AP interface is going down, the stations
are flushed (in ieee80211_do_stop()) only after
the beaconing was stopped.

However, drivers might rely on stations being
removed before the beaconing was stopped, in
order to clean up properly.

Fix it by flushing the stations on ap stop.

(we already do the same for other interface
types, e.g. in ieee80211_set_disassoc())

on disassoc, ieee80211_set_disassoc() goes out of PS
before indicating BSS_CHANGED_ASSOC (not sure why this
is needed, but some drivers might count on the current
behavior).

However, it does it after sending the disassoc
frame, which results in null-data frame being sent
(in order to go out of ps) after we were already sent
the disassoc, which is invalid.

Fix it by going out of ps before sending the disassoc.

commit "mac80211: unify SW/offload remain-on-channel"
moved the cookie assignment from ieee80211_mgmt_tx()
to ieee80211_start_roc_work().  But the latter is only
called where offchannel is needed.  If offchannel isn't
needed/used, a uninitialized cookie value would be returned
to userspace.

This patch sets the cookie value when offchannel isn't used.

This essentially reverts commit 2e165b818456 but
introduces the get_channel operation with a new
wireless_dev argument so that you can retrieve
the channel per interface. This is necessary as
even though we can track all interface channels
(except monitor) we can't track the channel type
used.
