eficonfig_append_menu_entryi() accepts the number of entries less than or equal to EFICONFIG_ENTRY_NUM_MAX. EFICONFIG_ENTRY_NUM_MAX is currently set as INT_MAX, so the invalid menu count check(efi_menu->count > EFICONFIG_ENTRY_NUM_MAX) in eficonfig_process_common() is always false. This commit sets EFICONFIG_ENTRY_NUM_MAX to (INT_MAX - 1).
