Subject: drm/amdgpu - Disable all irqs before disabling all CRTCs
Git-commit: e5b03032e34da84ee765ffbe4e36d344fdd04108
Patch-mainline: v4.17-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

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.
