cfg80211/mac80211: ignore signal if the frame was heard on wrong channel

On 2.4Ghz band, the channels overlap since the delta
between different channels is 5Mhz while the width of the
receiver is 20Mhz (at least).

This means that we can hear beacons or probe responses from
adjacent channels. These frames will have a significant
lower RSSI which will feed all kinds of logic with inaccurate
data. An obvious example is the roaming algorithm that will
think our AP is getting weak and will try to move to another
AP.

In order to avoid this, update the signal only if the frame
has been heard on the same channel as the one advertised by
the AP in its DS / HT IEs.
We refrain from updating the values only if the AP is
already in the BSS list so that we will still have a valid
(but inaccurate) value if the AP was heard on an adjacent
channel only.

To achieve this, stop taking the channel from DS / HT IEs
in mac80211. The DS / HT IEs is taken into account to
discard the frame if it was received on a disabled channel.
This can happen due to the same phenomenon: the frame is
sent on channel 12, but heard on channel 11 while channel
12 can be disabled on certain devices. Since this check
is done in cfg80211, stop even checking this in mac80211.

iwlwifi: mvm: configure low latency dependent scan parameters

In case of system low latency configure passive scan to be fragmented.
Set the following scan parameters for both immediate and scheduled scan:
 - passive scan fragment duration = 20ms
 - out-of-channel time = 70ms
 - suspend time = 105ms
Restructure channel's active/passive dwell time configuration to better
suit the above change.

The idea is that under low latency traffic passive scan is fragmented,
i.e. that dwell on a particular channel will be fragmented. Each
fragment dwell time is 20ms and fragments period is 105ms. Skipping to
next channel will be delayed by the same period (105ms). So suspend_time
parameter describing both fragments and channels skipping periods is set
to 105ms. This value is chosen so that overall passive scan duration
will not be too long. Max_out_time in this case is set to 70ms, so for
active scanning operating channel will be left for 70ms while for
passive still for 20ms (fragment dwell).
