efl/cserve2: Fix invalid iteration over client references

The _request_failed() function is called by error responses from slaves,
and iterating over references of a entry and removing each of them must
be done with EINA_LIST_FOREACH_SAFE(), since _entry_free_cb() calls
_entry_reference_del() which then removes the reference that is used in
the next iteration in for-loop from _request_failed().
