[PATCH 2/6] ath5k: Always free tx buffers before reset

[Nick Kossifidis <mickflemm@gmail.com>]

 * Always free tx buffers before reset, since we also empty hw queues.
 If we don't and a queue gets stuck, we'll never decrease txq_len and sw
 will keep thinking the queue is still stuck even after reset.
