Subject: net: add netif_tx_queue_frozen_or_stopped

When testing struct netdev_queue state against FROZEN bit, we also test
XOFF bit. We can test both bits at once and save some cycles.

Subject: workqueue: convert cancel_rearming_delayed_work[queue]() users to
 cancel_delayed_work_sync()

cancel_rearming_delayed_work[queue]() has been superceded by
cancel_delayed_work_sync() quite some time ago.  Convert all the
in-kernel users.  The conversions are completely equivalent and
trivial.
