The io_syscallX wrappers in syscall-mips.h discard error return status by overwriting the value returned in v0 from the system call with -1.
Modify this behavior by returning the negative of the return value on error (as identified by a3 != 0). This convention is consistent with the behavior observed in syscall-ppc.h.
