commit bb83337058a7000644cdeffc67361d2473534756 upstream.

For our pure advisory use-case, we only rely on this call as a hint, so
fix the warning complaints of using the smp_processor_id variants with
preemption enabled.

Fixes: db5ad6b7f8cd ("nvme-tcp: try to send request in queue_rq context")
Fixes: ada831772188 ("nvme-tcp: Fix warning with CONFIG_DEBUG_PREEMPT")
