drm/amdgpu: Increase UALink soft ring size

Browse source

The UALink soft ring overflows under bursts of interrupts from remote
GPUs. Size it at 16x the default soft ring to absorb the burst.

While here, read the source accel_id and context dwords before the
delegate path and log them, so the originating GPU is recorded for every
interrupt.
