[PATCH-for-9.0 02/25] memory: Have memory_region_init_ram_nomigrate() handler return a boolean

[Philippe Mathieu-Daudé]

Following the example documented since commit e3fe3988d7 ("error:
Document Error API usage rules"), have cpu_exec_realizefn()
return a boolean indicating whether an error is set or not.
