Fix two off-by-one errors:
+ One caused an out-of-bounds read when the loadparm value was 63
+ The other made a boot entry unselectable.
Currently, these bugs have no practical impact because:
1. The memory area beyond __stage2_params.config[63] is empty.
2. BOOT_MENU_ENTRIES is set to 63, which exceeds the number of boot menu
entries that can be written to disk.
