ath5k: fixing retries in ath5k_hw_setup_4word_tx_desc
The rate control algorithm, default is Minstrel for ath5k, determines
the number of retries to use for each rate. However, there exists in
ath5k_hw_setup_4word_tx_desc (which is called for AR5212 like devices)
a set number of retries defined by AR5K_TUNE_HWTXTRIES. The set
number of tries is added to the tx_tries0 variable setup by the rate
control algorithm. This changes the number of retries the rate
control algorithm considers necessary. By removing the
AR5K_TUNE_HWTXTRIES from the retry calculation the rate control
algorithm is given control over the number of retries.
