ia64: fix syscall_get_error()

According to documentation in include/asm-generic/syscall.h, syscall_get_error() should return -ERRORCODE if the system call failed.

This change fixes syscall_get_error() implementation on ia64 to match its own syscall_set_return_value(), the documentation, and other architectures where syscall_get_error() returns a non-positive value.

Fixes cfb361f13c81 ("[IA64] utrace syscall.h support for ia64")
