This patch performs sequential mapping between CPUs and queues.
In case the system has more CPUs than HWQs then there are still
CPUs to map to HWQs. In hyperthreaded system, map the unmapped CPUs
and their siblings to the same HWQ.
This actually fixes a bug that found unmapped HWQs in a system with
2 sockets, 18 cores per socket, 2 threads per core (total 72 CPUs)
running NVMEoF (opens upto maximum of 64 HWQs).

Christoph/Sagi/Keith,

any updates on this patch? Without it I' not able to run NVMf on a box with 44
Cores and 88 Threads w/o adding -i 44 to the nvme connect statement.

Thanks,
	Johannes
