ath9k: fix tx power settings for AR9287

Browse Source 
The 'ath9k_hw_update_regulatory_maxpower'
helper function has been introduced by
commit a55f858852
(ath9k_hw: Cleanup TX power calculation for AR9287).

Updating of the max_power_level value has been moved
into the helper function in that change, however the
removed code from 'ath9k_hw_ar9287_set_txpower' has
not been replaced with a call of the new helper
function.

Due to that missing call, retrieving tx power for 2x2
and 3x3 chainmask is not handled properly. During the
calculation of the tx power for 2x2 and 3x3 chainmasks
the values are reduced. Those reductions must be
compensated during retrieving.

Fix this by adding the missing call of the helper
function.
