[PATCH net] iwlwifi: add dependency of THERMAL with IWLMVM

[PATCH net] iwlwifi: add dependency of THERMAL with IWLMVM

[Mao Wenan]

If CONFIG_IWLMVM=y, CONFIG_THERMAL=n, below error can be found:
drivers/net/wireless/intel/iwlwifi/mvm/fw.o: In function `iwl_mvm_up':
fw.c:(.text+0x2c26): undefined reference to `iwl_mvm_send_temp_report_ths_cmd'
make: *** [vmlinux] Error 1

After commit 242d9c8b9a93 ("iwlwifi: mvm: use FW thermal
monitoring regardless of CONFIG_THERMAL"), iwl_mvm_up()
calls iwl_mvm_send_temp_report_ths_cmd(), but this function
is under CONFIG_THERMAL, which is depended on CONFIG_THERMAL.

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

Luca, should I apply this directly to wireless-drivers?

No, this patch defeats the point of the patch it fixes.

We have a proper fix already internally, which I haven't sent out yet,
that moves a couple of #ifdef's around to solve the issue.  I'll send
the patch in a sec.
