Subject: drm/amdgpu: remove hardcoded queue_mask in PACKET3_SET_RESOURCES
Git-commit: de65513af1124b28f2a858bc19b71a54dd93824e
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The assumption that we are only using the first pipe no longer holds.
Instead, calculate the queue_mask from the queue_bitmap.
