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()

perfectly ok.
