The 'name' variable in vtd_find_add_as function is not initialized
now, so when in gdb, we will got following output:
(gdb) p name
$1 =
"vtd-00.0\000\000\000\000\000\000\000\000\060\330\377\377\377\177\000\000\001\000\000\000\000\000\000\000p\330\377\377\377\177\000\000\353\362\372VUU\000\000p\330\377\377\377\177\000\000

\000\000\060b\000"
After this patch, it is more clear:
(gdb) p name
$1 = "vtd-00.0", '\000' <repeats 119 times>
