funcs/func_curl: Fix memory leak when CURLOPT channel datastore is destroyed

When the channel datastore associated with the usage of CURLOPT on a specific
channel is freed, the underlying structure holding the list of options is not
disposed of. This patch properly frees the structure in the datastore .destroy
callback.
