error in free_counting_bloom.

[wsm234]

There is a serious error in free_counting_bloom, and memory leak will happen.
Please modify the code as follows:
don't free bloom->bitmap directly.
call free_bitmap( bloom->bitmap ) instead.

//
int free_counting_bloom(counting_bloom_t *bloom)
{
if (bloom != NULL) {
free(bloom->hashes);
bloom->hashes = NULL;
//
//free(bloom->bitmap);
free_bitmap( bloom->bitmap );
//
free(bloom);
bloom = NULL;
}
return 0;
}
