[You-Sheng Yang]

From: YueHaibing <yuehaibing at huawei.com>

BugLink: https://bugs.launchpad.net/bugs/1879633

drivers/net/wireless/ath/ath11k/thermal.h:45:1:
 warning: no return statement in function returning non-void [-Wreturn-type]
drivers/net/wireless/ath/ath11k/core.c:416:28: error:
 passing argument 1 of 'ath11k_thermal_unregister' from incompatible pointer type [-Werror=incompatible-pointer-types]

Add missing return 0 in ath11k_thermal_set_throttling,
and fix ath11k_thermal_unregister param type.
