nvme: add support for streams and directives

This adds support for Directives in NVMe, particular for the Streams
directive. We default to allocating 4 streams per name space, but
it is configurable with the 'streams_per_ns' module option.

If a write stream is set in a write, flag is as such before
sending it to the device.

Some debug stuff in this patch, dumping streams ID params when
we load nvme.
