drm/amdgpu: Fix module unload hang by KIQ IRQ set
In some cases, manually insmod/rmmod amdgpu is necessary. When
unloading amdgpu, the KIQ IRQ enable/disable function will case
system hang. The root cause is, in the sequence of function
amdgpu_fini, the sw_fini of IP block AMD_IP_BLOCK_TYPE_GFX will be
invoked earlier than that of AMD_IP_BLOCK_TYPE_IH. So continue to use
the variable freed by AMD_IP_BLOCK_TYPE_GFX will cause system hang.
