drm/amd/amdgpu: Fix out of bounds warning in amdgpu_hw_ip_info
Fix an array index out of bounds warning in the DMA IP case of
amdgpu_hw_ip_info() where it was incorrectly checking
adev->gfx.gfx_ring[i].no_user_submission instead of
adev->sdma.instance[i].ring.no_user_submission.
The mismatch caused UBSAN to report an array bounds violation since
it was accessing the GFX ring array with SDMA instance indices.
Fixes: 4310acd4464b ("drm/amdgpu: add ring flag for no user submissions")
