WAN: flush tx_queue in hdlc_ppp to prevent panic on rmmod hw_driver. tx_queue is used as a temporary queue when not allowed to queue skb directly to the hw device driver (which may sleep). Most paths flush it before returning, but ppp_start() currently cannot. Make sure we don't leave skbs pointing to a non-existent device. Thanks to Michael Barkowski for reporting this problem.
