iwlwifi: fix queue flush confusion
The flush_control parameter to iwlagn_txfifo_flush
is passed as an internal value (context flags) and
then sent to the device, that can't be right.
Fix the confusion by removing the parameter, always
use IWL_DROP_ALL that is redefined according to the
firmware API in the flush control.
