check_icmp: Fix compiler warning

This fixes a compiler warning which complains about an uninitialized
value for a variable which is then returned.
This had no real world impact, since the program would crash in the
branch where result is not set.
The variable is initialized to "-1" which would be the error for
inet_pton.
