[PATCH] MIPS getdomainname() off by 1;

["Randy.Dunlap" <rddunlap@osdl.org>]

irix_getdomainname() max size appears to be off by 1;
other similar code in kernel uses __NEW_UTS_LEN as the max size,
and <domainname> includes an extra byte for the terminating
null character.

Does sysirix.c need to limit <len> to 63 instead of 64 for some
reason?
