Subject: [PATCH] iwlwifi: fix building without CONFIG_THERMAL

The iwl_mvm_send_temp_report_ths_cmd() function is now called without
CONFIG_THERMAL, but not defined:

ERROR: "iwl_mvm_send_temp_report_ths_cmd" [drivers/net/wireless/intel/iwlwifi/mvm/iwlmvm.ko] undefined!

Move that function out of the #ifdef as well and change it so
that empty data gets sent even if no thermal device was
registered.

Fixes: 242d9c8b9a93 ("iwlwifi: mvm: use FW thermal monitoring regardless of CONFIG_THERMAL")

No idea if this does what was intended in the commit that introduced
the link failure, please see for youself.
