NVMe: Correctly handle IOCTL_SUBMIT_IO when cpus > online queues
nvme_submit_io_cmd() uses smp_processor_id() to pick an IO queue index.
This patch fixes the case where there are more cpus from which the ioctl
call can originate than online queues, which can happen when a device
supports or was allocated fewer interrupt vectors than exist cpu cores.
Thanks to Keith Busch for the implementation suggestion.
