[PATCH v3 05/27] cpu: Directly use get_paging_enabled() fallback handlers in place

[Philippe Mathieu-Daudé]

No code uses CPUClass::get_paging_enabled() outside of hw/core/cpu.c:

  $ git grep -F -- '->get_paging_enabled'
  hw/core/cpu.c:74:    return cc->get_paging_enabled(cpu);
  hw/core/cpu.c:438:    k->get_paging_enabled = cpu_common_get_paging_enabled;
  target/i386/cpu.c:7418:    cc->get_paging_enabled = 
x86_cpu_get_paging_enabled;

Check the handler presence in place and remove the common fallback code.
