Marc Hartmayer 8d58a9abb0 zipl/boot: Fix two off-by-one bugs

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.
