[PATCH 01/13] clone3: clone3_cap_checkpoint_restore: Fix build errors seen with -Werror

[Guenter Roeck]

Fix:

clone3_cap_checkpoint_restore.c:56:7: error: unused variable 'ret'
   56 |                 int ret;
      |                     ^~~
clone3_cap_checkpoint_restore.c:57:8: error: unused variable 'tmp'
   57 |                 char tmp = 0;
      |                      ^~~
clone3_cap_checkpoint_restore.c:138:6: error: unused variable 'ret'
  138 |         int ret = 0;

by removing the unused variables.
