Ben Walker 3870092dd1 bdev/nvme: For reads, if there is only one element in the iov don't use
readv API

It's cheaper to call spdk_nvme_ns_cmd_read_with_md than it is to call
spdk_nvme_ns_cmd_readv_with_md, so do a quick check of the iovcnt and
use the best one for the job.

This is about a 15% improvement in I/Ops.
