info.c: worked around missing sub-devices in -lx

Browse Source 
output [Fabio Priuli]

out of whatsnew:
I fear no proper and clean solution is possible as long as the
driver has such a privileged role in the MAME core structure,
because stuff that is not attached to a root_device (=driver)
is hard to parse. Anyway, there should be no more missing
roms from -lx output (until people starts adding them as
sub-sub-subdevices... ;) )
