MIPS: Use force_sig when handling address errors.
When init is started it is SIGNAL_UNKILLABLE. If it were to get an address error, we would try to send it SIGBUS, but it would be ignored and the faulting instruction restarted. This results in an endless loop. We need to use force_sig() instead so it will actually die and give us some useful information.
