fix double-free in ares_dns_rr_set_opt{_own}() recently introduced

When implementing ares_dns_rr_del_opt_byid() for DNS cookie support,
memory wasn't being zero'd out after removing an option, and when
ares_dns_rr_set_opt{_own}() was called, it would try to free the
address that still existed.  Add a couple memset()'s to prevent
this issue.

Fixes #836
