Quit with an error message if ioctl(TUNSETIFF) fails.

It is possible that opening /dev/net/tun works but that interface
creation itself fails, for example if a non-root user tries to create a
new interface, or if the desired interface is already opened by another
process. In this case, the ioctl() fails, but we actually silently
ignored this condition.
