[PATCH 3/4] hw/i386/x86: Eliminate two if statements in x86_bios_rom_init()

[Bernhard Beschow <shentey@gmail.com>]

Given that memory_region_set_readonly() is a no-op when the readonlyness is
already as requested it is possible to simplify the pattern

  if (condition) {
    foo(true);
  }

to

  foo(condition);

which is shorter and allows to see the invariant of the code more easily.
