stubs/atom.c: Fix memory leak in __libxfont_internal__MakeAtom

Reported by a static analysis tool:

     9. libXfont2-2.0.6/src/stubs/atom.c:179:5:
        alloc_fn: Storage is returned from allocation function "malloc".
    10. libXfont2-2.0.6/src/stubs/atom.c:179:5:
        var_assign: Assigning: "a" = storage returned from
        "malloc(24UL + len + 1UL)".
    16. libXfont2-2.0.6/src/stubs/atom.c:194:6:
        leaked_storage: Variable "a" going out of scope leaks the
        storage it points to.
    #   192|  if ((ResizeHashTable() == FALSE) &&
    #   193|     ((hashTable == NULL) || (hashUsed == hashSize)))
    #   194|-> 	 return None;
    #   195|  h = hash & hashMask;
    #   196|  if (hashTable[h]) {
