[ Upstream commit 01605ad6c3e8608d7e147c9b75d67eb8a3d27d88 ]
In the normal MLME code we always call
ieee80211_mgd_set_link_qos_params() before
ieee80211_link_info_change_notify() and some drivers,
notably iwlwifi, rely on that as they don't do anything
(but store the data) in their conf_tx.
Fix the order here to be the same as in the normal code
paths, so this isn't broken.

[ Upstream commit 9288188438d85e22c23cfd6657ee8a801babc83c ]
Move color collision report in a dedicated delayed work and do not run
it in interrupt context in order to rate-limit the number of events
reported to userspace. Moreover grab wdev mutex in
ieee80211_color_collision_detection_work routine since it is required
by cfg80211_obss_color_collision_notify().

Implement an API function and debugfs file to switch
active links.
Also provide an async version of the API so drivers
can call it in arbitrary contexts, e.g. while in the
authorized callback.

In order to let the driver select active links and properly
make multi-link connections, as a first step isolate the
driver from inactive links, and set the active links to be
only the association link for client-side interfaces. For
AP side nothing changes since APs always have to have all
their links active.
To simplify things, update the for_each_sta_active_link()
API to include the appropriate vif pointer.
This also implies not allocating a chanctx for an inactive
link, which requires a few more changes.
Since we now no longer try to program multiple links to the
driver, remove the check in the MLME code.

We probably should've done that originally, we already have
about 300 lines of code there, and will add more. Move all
the link code we wrote to a new file.
