[PATCH 1/2] ccli: cache: Fix -Wuninitialized warning

[Ammar Faizi <ammarfaizi2@gnuweeb.org>]

The idx variable is uninitialized and incremented. Clang warns it:

  cache.c:214:28: warning: variable 'idx' is uninitialized when used here [-Wuninitialized]
    214 |         for (i = 0; i < cnt; i++, idx++) {
        |                                   ^~~
  cache.c:184:9: note: initialize the variable 'idx' to silence this warning
    184 |         int idx;
        |                ^
        |                 = 0

Remove the idx variable entierly, it's not used.
