[IA64] ia32_signal.c: erroneous use of memset/memcpy
Found by Alexander Nyberg, improved by Bjorn Helgaas. - Fix the incorrect argument to sizeof() - looks like memcpy() code pass was dervived from code that used copy_from_user(). But in this case we are doing to kernel space to kernel space copy, so memcpy is the right routine, but it doesn't return an error code.
