mt76: sdio: remove wake logic in mt76s_process_tx_queue

Similar to mmio/usb code path, remove wake logic in mt76s_process_tx_queue
routine. Starting from commit 90d494c9 ("mt76: improve tx queue
stop/wake"), the wake queue logic on the sdio status path is no longer
necessary since the hw queues are no longer stopped on the mt76 tx path.
