patch to add NVMe support to pass

This patch adds IO pass-through support for NVMe to CAM for both administrative
and NVM (a.k.a. "IO") commands. To differentiate between the command types, the
patch adds a new function code XPT_NVME_ADMIN for administrative commands and
uses the existing function code for NVM commands.
