[PATCH] drm/amdgpu - Disable all irqs before disabling all CRTCs

From: Mikita Lipski <mikita.lipski at amd.com>

By moving amdgpu_irq_disable_all earlier in the sequence
fixes an issue with disabling pflip interrupts:

*ERROR* dal_irq_service_dummy_ack: called for non-implemented irq source

Earlier patch fixed a memory corruption and revealed irq
warnings.This way it seems to be there no obvious issues
with unloading the module.
