Maciej W. Rozycki 8eb8cd6c30 MIPS: traps: Fix SIGFPE information leak from do_ov' and do_trap_or_bp' ...

commit e723e3f7f9 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.
