NVMe: Fix endian-related problems in user I/O submission path
When constructing the command, dsmgmt needs to be treated as a 32-bit value, not a 16-bit value. reftag, apptag and appmask all need to be converted from native-endian to little-endian. Again, sparse's bitwise warnings caught this problem. Thanks to Keith for pointing out the correct way to fix the reftag.
