Edwin Török fa8250f192 libs/guest: Fix leak on realloc failure in backup_ptes() 
From `man 2 realloc`:

  If realloc() fails, the original block is left untouched; it is not freed or moved.

Found using GCC -fanalyzer:

  |  184 |         backup->entries = realloc(backup->entries,
  |      |         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  |      |         |               | |
  |      |         |               | (91) when ‘realloc’ fails
  |      |         |               (92) ‘old_ptes.entries’ leaks here; was allocated at (44)
  |      |         (90) ...to here
