Hibernation stopped working reliably after commit
ab76f7b4ab23 (x86/mm: Set NX on gap between __ex_table and rodata).
We found this issue on DINO2 MLK machines, and could be reproduce
easier with larger built-in RAM.

The commit works like a charm that fixes this issue.

Tested on DINO2 MLK laptops.
