Johan Hovold 42a97c0480 USB: serial: keyspan_pda: fix data loss on receive throttling
Killing the interrupt-in urb when the line disciple requests throttling
may lead to data loss if an ongoing transfer is cancelled.

Instead set a flag to prevent the completion handler from resubmitting
the urb until the port is unthrottled.
