ath9k: fix a tx rate duration calculation bug
commit 76591bea9714a58d8924154068c78d702eb2cb17 upstream.
The rate pointer variable for a rate series is used in a loop before it is
initialized. This went unnoticed because it was used earlier for the RTS/CTS
rate. This bug can lead to the wrong PHY type being passed to the
duration calculation function.
