drm/amdgpu/userq: preserve kernel rings during gfx pipe reset

Browse source

Route GFX user queue resets through amdgpu_gfx_reset_mes_gfx() when
HQD detection and PER_PIPE are available, preserving collateral kernel
rings across a pipe reset.

If the HQD cannot be located, use MES packet reset and protect kernel
rings on all GFX pipes.
