[PATCH-for-5.1 v3 08/24] hw/arm/fsl-imx6: Simplify checks on 'smp_cpus' count

[Philippe Mathieu-Daudé]

Coccinelle failed at processing this file:

  $ spatch ... --timeout 60 --sp-file \
    scripts/coccinelle/simplify-init-realize-error_propagate.cocci
  HANDLING: ./hw/arm/fsl-imx6.c
  Fatal error: exception Coccinelle_modules.Common.Timeout

While reviewing we notice the smp_cpus count is already limited
by MachineClass::max_cpus:

  static void sabrelite_machine_init(MachineClass *mc)
  {
      mc->max_cpus = FSL_IMX6_NUM_CPUS;
      ...
  }

So remove the check in realize(), but still assert in init().
