bug in devinfo -u: 'open if_tun units'

[Bruce Cran]

I've found what looks like it might be a bug in devinfo - listing resources
by type, there are far too many 'open if_tun unit' resources: there are over
126,000 lines, repeating

0 (root0)
1-32767 (root0)

for about 500 lines, before there's another 'open if_tun units:' header.  The 
file produced by 'devinfo -u > devinfo.log' is 2MB.  I've got 2 if_tun 
interfaces running.
