session_leave_vt may be called after the VT device was hung up, which will cause vt_release to fail with -EIO. This is known to cause an issue with GNOME 44 on Fedora where gdm-session-worker sometimes freezes when trying to switch to VT 1 after a `loginctl terminate-user` operation. Fix this by reopening the VT in session_leave_vt if we get an -EIO.
