pst 489b7a4fe8 Attempt to open the device for reading before actually adding the device
to the session list.  If the device comes back as unconfigured, just
ignore that line in /etc/ttys.  If someone HUP's init, we'll try again.

This change stops getty's from hanging on vty and sio ports that don't
exist, either due to LKM drivers not being loaded, or probes failing.
