drm/amdgpu: Remove VRAM from shared bo domains.

[ Upstream commit 9b3f217faf48603c91d4ca44a18e6ff74c3c1c0c ]

This fixes an issue introduced by change "allow framebuffer in GART
memory as well" which could lead to a shared buffer ending up
pinned in vram.  Use GTT if it is included in the domain, otherwise
return an error.
