wifi: iwlwifi: mld: evacuate NAN channels on link switch
The FW API doesn't allow a station (of certain types, including
STATION_TYPE_PEER) to not be correlated to any link. Therefore,
when switching links, mac80211 first adds the new link and then
removes the old one.
In case we have a NAN interface that operates on 3 links and a
BSS interface that operates on the 4th link, there won't be any
room to perform a link switch that temporarily needs two links
for the BSS interface, but the firmware only has four total.
To mitigate this, try to evacuate a NAN channel in this scenario:
First try to evacuate a NAN channel using the same phy as the BSS
link being deactivated, since we expect NAN to follow the BSS
channel configuration. If that doesn't work, try to evacuate any
NAN channel.
