I wonder if libxl__device_nextid is robust enough to handle holes. If
there are 3 devices (0,1,2) of type X, and device #0 or #1 is removed
with "X-detach", wouldn't the code return nextid==2? The result would be
that the caller will write to the wrong path.

I have not veified this theory in practice.
