memory: Simplify memory_region_init_rom_device_nomigrate() calls

Mechanical change using the following coccinelle script:

@@
expression mr, owner, arg3, arg4, arg5, arg6, errp;
@@
-   memory_region_init_rom_device_nomigrate(mr, owner, arg3, arg4, arg5, arg6, &errp);
    if (
-       errp
+       !memory_region_init_rom_device_nomigrate(mr, owner, arg3, arg4, arg5, arg6, &errp)
    ) {
        ...
        return;
    }

and removing the local Error variable.
