When a second instance of ptp4l using the same configuration was
(accidentally) started, it removed the Unix domain socket of the first
instance and prevented communication with it.
Advertising
Remove the unlink() call to let bind() of the second instance fail and
run with the UDS port in faulty state.
If the socket is not removed on ptp4l exit (e.g. due to crash), the user
will have to remove it manually in order to get a working UDS port
again.
