msm: kgsl: Keep postamble packets in a privileged buffer

Postamble packets are executed in privileged mode by gpu. So we should keep
them in a privileged scratch buffer to block userspace access. For
targets with APRIV feature support, we can mark the preemption scratch
buffer as privileged too to avoid similar issues in future.
