From: Colin Ian King <[email protected]>
The for_each_tx_queue loop iterates with a u8 loop counter i and
compares this with the loop upper limit of bp->num_queues that
is an int type. There is a potential infinite loop if bp->num_queues
is larger than the u8 loop counter. Fix this by making the loop
counter the same type as bp->num_queues.
