bdev/nvme: Use spdk_nvme_ns_get_max_io_xfer_size() for I/O passthrough

Browse Source 
This and the next change will enable us to pass spdk_nvme_ns and
spdk_nvme_qpair as parameters to I/O passthrough APIs. When we support
ANA multipath, ANA state of spdk_nvme_ns will be checked. These changes
follow that.
