nvme-tcp: fix misuse of __smp_processor_id with preemption enabled
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") Signed-off-by: Sagi Grimberg <sagi@grimberg.me> Reviewed-by: Chaitanya Kulkarni <chaitanya.kulkarni@wdc.com> Tested-by: Yi Zhang <yi.zhang@redhat.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
