MIPS: traps: Fix SIGFPE information leak from `do_ov' and `do_trap_or_bp'
BugLink: http://bugs.launchpad.net/bugs/1555640 commit e723e3f7 upstream. Avoid sending a partially initialised `siginfo_t' structure along SIGFPE signals issued from `do_ov' and `do_trap_or_bp', leading to information leaking from the kernel stack.
