[PATCH v2 2/6] hw/loader: Clean up global variable shadowing in rom_add_file()

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

Invert 'option_rom' logic and rename it as 'option_rom_has_mr' to fix:

  hw/core/loader.c:1073:27: error: declaration shadows a variable in the global scope [-Werror,-Wshadow]
                       bool option_rom, MemoryRegion *mr,
                            ^
  include/sysemu/sysemu.h:57:22: note: previous declaration is here
  extern QEMUOptionRom option_rom[MAX_OPTION_ROMS];
                       ^
