[PATCH 3/6] hw/display/vga: Clean up global variable shadowing

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Fix:

  hw/display/vga.c:2307:29: error: declaration shadows a variable in the global scope [-Werror,-Wshadow]
                MemoryRegion *address_space_io, bool init_vga_ports)
                            ^
  include/exec/address-spaces.h:35:21: note: previous declaration is here
  extern AddressSpace address_space_io;
                      ^
