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.
