USB: serial: keyspan_pda: fix write-wakeup use-after-free
commit 37faf50615412947868c49aee62f68233307f4e4 upstream.
The driver's deferred write wakeup was never flushed on disconnect,
something which could lead to the driver port data being freed while the
wakeup work is still scheduled.
Fix this by using the usb-serial write wakeup which gets cancelled
properly on disconnect.
