Hmm, after committing this I realized the init here clears the devid set
in libxlMakeNicList.  It wasn't spotted in my testing since libxl will
provide a sane devid when not specified.  In fact, for all the other
devices we allow libxl to determine devid.  I'll send a patch to remove
the nic devid assignment.  It's trivial, but maybe you can review it -
quick sanity check to ensure I'm not overlooking something.

Regards,
Jim
