net: add documentation for BQL helpers
Provide a kernel-doc comment documentation for the BQL helpers:
- netdev_sent_queue
- netdev_completed_queue
- netdev_reset_queue
Similarly to how it is done for the other functions, the documentation
only covers the function operating on struct net_device and not struct
netdev_queue.
