Philippe Mathieu-Daudé 1db889c71f hw/openrisc/openrisc_sim: Add assertion to silence GCC warning 
When compiling with GCC 10 (Fedora 32) using CFLAGS=-O2 we get:

    CC      or1k-softmmu/hw/openrisc/openrisc_sim.o
  hw/openrisc/openrisc_sim.c: In function ‘openrisc_sim_init’:
  hw/openrisc/openrisc_sim.c:87:42: error: ‘cpu_irqs[0]’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
     87 |         sysbus_connect_irq(s, i, cpu_irqs[i][irq_pin]);
        |                                  ~~~~~~~~^~~

While humans can tell smp_cpus will always be in the [1, 2] range,
(openrisc_sim_machine_init sets mc->max_cpus = 2), the compiler
can't.

Add an assertion to give the compiler a hint there's no use of
uninitialized data.
