units/serial-getty@.service: use the default RestartSec
For pluggable ttys such as USB serial devices, the getty is restarted and exits in a loop until the remove event reaches systemd. Under certain circumstances the restart loop can overload the system in a way that prevents the remove event from reaching systemd for a long time (e.g. at least several minutes on a small embedded system). Use the default RestartSec to prevent the restart loop from overloading the system. Serial gettys are interactive units, so waiting an extra 100ms really doesn't make a difference anyways compared to the time it takes the user to log in.
