nvme: tcp: Fix compilation warning with W=1
When compiling with W=1, a warning result for the function nvme_tcp_set_queue_io_cpu(): host/tcp.c:1578: warning: Function parameter or struct member 'queue' not described in 'nvme_tcp_set_queue_io_cpu' host/tcp.c:1578: warning: expecting prototype for Track the number of queues assigned to each cpu using a global per(). Prototype was for nvme_tcp_set_queue_io_cpu() instead Avoid this warning by using the regular comment format for the function nvme_tcp_set_queue_io_cpu() instead of the kdoc comment format.
