drm/amd/display: Fix warning in disabling vblank irq
[Why]
During gpu-reset, we toggle vblank irq by calling dc_interrupt_set()
instead of amdgpu_irq_get/put() because we don't want to change the irq
source's refcount. However, we see the warning when vblank irq is enabled
by dc_interrupt_set() during gpu-reset but disabled by amdgpu_irq_put()
after gpu-reset.
[How]
Only in dm_gpureset_toggle_interrupts() we toggle vblank interrupts by
calling dc_interrupt_set(). Apart from this we call dm_set_vblank()
which uses amdgpu_irq_get/put() to operate vblank irq.
