[PATCH 4/6] drm/i915/gvt: Prevent use of uninitilized member fb_info->obj

[Colin Xu]

fb_info is dumped from vgpu_get_plane_info() and copy to dmabuf_obj->info,
fb_info->obj is not used and (dmabuf_obj->info)->obj is assigned to itself.
To avoid use of uninitialized member, zero out fb_info before the dump.
