USB-serial fixes for v4.19-rc7

Here are some device-id patches for 4.19-rc7.

Some Quectel modems have a vendor command which can be used to disable
certain interfaces in their configurations, but unlike some other modems
this also causes the interface numbers to change. These patches allow us
to support all such interface permutations at least for the Quectel
EP06.

All have been in linux-next with no reported issues.
