[PATCH 1/2] drm/amdgpu: fix amdgpu_irq_put call trace in jpeg_v4_0_hw_fini

[Horatio Zhang]

During the suspend, the jpeg_v4_0_hw_init function will
use the amdgpu_irq_put to disable the irq of jpeg.inst, but it
was not enabled during the resume process, which resulted in a
call trace during the GPU reset process.
