BUG/MINOR: resolvers: Free opts on parse error in resolv_parse_do_resolve()

The error handler at do_resolve_parse_error freed varname and resolvers_id
but missed freeing rule->arg.resolv.opts (allocated via calloc). Added
ha_free(&rule->arg.resolv.opts) to the cleanup path.

This patch could be backported to all stable branches.
