In the PRI detector, after the current radar pulse
has been checked agains existing PRI sequences, it
is considered as part of a new potential sequence.

Previously, the condition to accept a new sequence
was to have at least the same number of pulses as
the longest matching sequence. This was wrong,
since it led to duplicates of PRI sequences.

This patch changes the acceptance criteria for new
potential sequences from 'at least' to 'more than'
the longest existing.

Detection performance remains unaffected, while
the number of PRI sequences accounted at runtime
(and with it CPU load) is reduced by up to 50%.

In the midst of chanctx patch review channel
switching became broken which I failed to notice
until now.

Function ath10k_mac_vif_chan() reports current
chandef which isn't updated until after
switch_vif_chanctx() is returned from.
Consequently the driver just restarted operation
on channels it was residing already instead of
switching to the new ones.

In practice there's no point in having a copy of
chanctx_conf.

Most of the time the channel pointer (and band
along with it) is accessed and this can't change
after a chanctx is created because switching is
done using explicit chanctx swapping via
switch_vif_chanctx().

The only thing that can change within a
chanctx_conf and is used by the driver is
radar_enabled and channel width. These are however
always accessed in adequate mac80211 callback
context which guarantees safe access to the
chanctx data.
