throttle_active_work() is only called if CONFIG_SYSFS is set,
otherwise we get a harmless warning:

arch/x86/kernel/cpu/mce/therm_throt.c:238:13: error: 'throttle_active_work' defined but not used [-Werror=unused-function]

Mark the function as __maybe_unused to avoid the warning.

Fixes: f6656208f04e ("x86/mce/therm_throt: Optimize notifications of thermal throttle")
