netfilter: xt_NFQUEUE: prefer raw_smp_processor_id

Browse Source 
[ Upstream commit c6c5327dd1 ]

With PREEMPT_RCU this triggers a splat because smp_processor_id() can be
preempted while inside a RCU critical section. If xt_NFQUEUE target is
invoked via nft_compat_eval() path, we are inside a RCU critical
section.

Just use the raw version instead.
