Initialize get_resolvconf_addr variable rv to NULL

Getting warning compiling for Android:

./util.c:35:6: warning: variable 'rv' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
        if (sscanf(buf, "%15s", addr) == 1)
            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./util.c:79:9: note: uninitialized use occurs here
        return rv;
               ^~
