Re: [sr-dev] [kamailio/kamailio] lrkproxy: compile warning (#2663)

@mojtabaesfandiari - the module is merged in master branch of Kamailio, do not push commits to the branch that was used for pull request. Clone kamailio source code from master branch and do changes there, then you can make pull requests or push the commits to your module.

As I saw your push to the pull request, the new codition is also exposed to same warning:

``` (e->node->lrkp_n_c->external_ip != NULL) ```

The field `external_ip` is also a char[20] buffer and therefore it is never NULL.
