Subject: iwlwifi: mvm: init card correctly on ctkill exit check

From: Arik Nemtsov <[email protected]>

commit 1a3fe0b2b6778b7866e2b3f5c9a299d5e9bbd89c upstream.

During the CT-kill exit flow, the card is powered up and partially initialized to check if the temperature is already low enough. Unfortunately the init bails early because the CT-kill flag is set. Make the code bail early only for HW RF-kill, as was intended by the author. CT-kill is self-imposed and is not really RF-kill.

Fixes 31b8b343e019 ("iwlwifi: fix RFkill while calibrating")
