[PATCH] drm/amdgpu: Check fb-sharing for xgmi accessiblity

[will.aitken]

From: Will Aitken <will.aitken@amd.com>

In sriov, sometimes fb-sharing will be disabled. In those scenarios xgmi
links should no longer be used. Adding check for sharing-enabled to
determine if there is xgmi accessibility between devices
