wifi: iwlwifi: mld: update the TLC when we deactivate a link

Browse source 
We hit a problem in the channel switch flow.
We had link 0 using PHY 0, so the TLC object in the firmware is using
PHY 0.
Then we switched channel, so mac80211 / iwlmld:
* deactivated link 0
* removed PHY 0
* added PHY 1
* modified link 0 to use PHY 1
* activated link 0.

The TLC object was not updated and the firmware was unhappy that the TLC
was still trying to use PHY 0.

Fix that by letting the TLC know about the PHY context before the link
activation.
When we are de-activating a link, let the TLC know so that it'll send a
TLC configuration command with an invalid PHY context to remove the
relationship between the TLC object and the PHY that is going to be
removed.

That last part is not implemented yet in the firmware, so leave this as
a TODO for now.
