drm/amdgpu: Retain job->vm in amdgpu_job_prepare_job
The field job->vm is used in function amdgpu_job_run to get the page
table re-generation counter and decide whether the job should be skipped.
Specifically, function amdgpu_vm_generation checks if the VM is valid for this job to use.
For instance, if a gfx job depends on a cancelled sdma job from entity vm->delayed,
then the gfx job should be skipped.
