iwlwifi: mvm: reset the temperature when temperature test is disabled
Since we can't read the actual temperature when the firmware is
running, just set the temperature to 0 when the test is disabled and
disable CT Kill if it was enabled.
Additionally, since we rely on iwl_mvm_tt_handler() to exit CT kill
when in test mode, call iwl_mvm_exit_ctkill() in that function if the
temperature is low again. Also make the iwl_mvm_enter_ctkill() and
iwl_mvm_exit_ctkill() return if called when not necessary anymore
(e.g. when iwl_mvm_exit_ctkill() is called when we're not in CT-kill).
