[PATCH] cec tools: exit when CEC device is disconnected

[Johan Fjeldtvedt <jaffe1@gmail.com>]

When devices are disconnected, -EIO is currently returned by ioctl, but
this will be replaced by -ENODEV. When ioctl returns that, there is no
reason to let cec-ctl, cec-follower or cec-compliance run, so just exit
them.

This patch must be applied when the CEC framework has been changed to return
ENODEV instead of EIO when devices are disconnected.
