Mark a job as secure, if and only if the command submission flag has the secure flag set.
v2: fix the null job pointer while in vmid 0 submission. v3: Context --> Command submission. v4: filling cs parser with cs->in.flags v5: move the job secure flag setting out of amdgpu_cs_submit()

At some point we need to cleanup struct amdgpu_job, but for now that is perfectly ok.
