USB-serial fixes for v4.14-rc5

Here's a fix for a cp210x regression that prevented a class of devices
from being successfully probed. Two use-after-free bugs in the console
code are also fixed.

Included are also some new device ids.

All but the last three commits have been in linux-next with no reported
issues.
