Dmitry Torokhov b7c625ce6d Input: ims-psu - check if CDC union descriptor is sane
commit ea04efee7635c9120d015dcdeeeb6988130cb67a upstream.

Before trying to use CDC union descriptor, try to validate whether that it
is sane by checking that intf->altsetting->extra is big enough and that
descriptor bLength is not too big and not too small.
