wifi: mt76: mt7915: rework init flow in mt7915_thermal_init()
[ Upstream commit 9c97df11dfe68b548a47744ba9fa6beddcfba2bc ]
If kernel do not enable CONFIG_HWMON, it may cause thermal
initialization to be done with temperature value 0 and then can not
transmit. This commit fixes it by setting trigger/restore temperature
before checking CONFIG_HWMON.
