rS368058: Ensure consistent error messages from ifconfig(8).
Summary

If multiple threads are invoking ifconfig XXX create a race may occur which can lead to two different error messages for the same error.

a) ifconfig: SIOCIFCREATE2: File exists
b) ifconfig: interface XXX already exists

This patch ensures ifconfig prints the same error code for the same case.
