Fix segfault with cable test and ./configure --disable-netlink
When the netlink interface code is disabled, a stub version of
netlink_run_handler() is used. This stub version needs to handle the
case when there is no possibility for a command to fall back to the
IOCTL call. The two cable tests commands have no such fallback, and if
we don't handle this, ethtool tries to jump through a NULL pointer
resulting in a segfault.
