Subject: [PATCH] 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.

(cherry picked from commit 4bf04322b8b7ecca4f3d65cfc642d0ac16356129)
