drm/amdgpu: fix ring timeout issue in gfx10 sr-iov environment
commit 26c95e838e63 ("drm/amdgpu: set the VM pointer to NULL in
amdgpu_job_prepare") set job->vm as NULL if there is no fence. It will
cause emit switch buffer be skippen if job->vm set as NULL.
Check job rather than vm could solve this problem.
