mac80211: delete the assoc/auth timer upon suspend
While suspending, we destroy the authentication /
association that might be taking place. While doing so, we
forgot to delete the timer which can be firing after
local->suspended is already set, producing the warning below.
Fix that by deleting the timer.

Oliver reported that it breaks network-manager, for some reason with

(ethernet), sees no carrier (as expected with wifi) and fails to do
anything else with it.
Revert this to unbreak userspace.

iwlwifi: mvm: abort scheduled scan upon RFKILL
When we have an active scheduled scan, and the RFKILL
interrupt kicks in, the stack will cancel the scheduled
scan as part of the down flow. But cancelling scheduled
scan usually implies sending a command to the firwmare
which has been killed as part of the RFKILL interrupt
handling.
Because of that, we returned an error to mac80211 when
it asked to stop the scheduled scan and didn't notify the
end of the scheduled scan. Besides a fat warning, this led
to a situation in which cfg80211 would refuse any new scan
request.
To disentangle this, fake that the scheduled scan has been
stopped without sending the command to the firwmare, return
0 after having properly let cfg80211 know that the scan
has been cancelled.
This is basically the same as:

cfg80211: change bandwidth reporting to explicit field
For some reason, we made the bandwidth separate flags, which
is rather confusing - a single rate cannot have different
bandwidths at the same time.
Change this to no longer be flags but use a separate field
for the bandwidth ('bw') instead.
While at it, add support for 5 and 10 MHz rates - these are
reported as regular legacy rates with their real bitrate,
but tagged as 5/10 now to make it easier to distinguish them.
In the nl80211 API, the flags are preserved, but the code
now can also clearly only set a single one of the flags.

These rates are treated the same as 160 MHz in the spec, so

yet, this is also not a problem, just remove them.
In the userspace API the field remains reserved to preserve
API and ABI.
