ath5k: check return value of ieee80211_get_tx_rate
This avoids a NULL pointer dereference as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=625889
When the WARN condition is hit in ieee80211_get_tx_rate, it will return
NULL. So, we need to check the return value and avoid dereferencing it
in that case.
