* Begin fleshing out ath_buf_clone() - a method of cloning
  buffers for reuse during software retransmit

* Break out the buffer reclaimation code into ath_freebuf(),
  which doesn't recycle the mbuf/node or call the net80211
  callback.

* Change _ath_getbuf_locked() to use ath_freebuf(). This
  changes the order of DMA unmap and buffer free, so keep
  that in mind.

The (eventual) aim of ath_freebuf() is to allow a buffer
to be cloned, and the original buffer to then be returned.
The caller can blank the node/mbuf and call ath_freebuf().
