ixgbe: fix tx queue index
Don't do the num_tx_queues based masking on calculating tx queue
index.
1) num_tx_queues is not always power-of-2, because it also depends on
the online cpu numbers. So the masking could be a performance bug
on a 6 cpu system.
2) queue_mapping will be limited by real_num_tx_queues=num_tx_queues
in the generic netdev function set_cur_queue_map(). So the bound
limiting here is not necessary.
