LinuxKPI: Allow wake_up to be executed within a critical section

LinuxKPI: Allow wake_up to be executed within a critical section

by replaceing of spin_lock() call with spin_lock_irqsave()

This fixes following panic in drm-kmod:

panic: mi_switch: switch in a critical section
cpuid = 2
time = 1636939794
