Rx and Tx queues share the common tap file descriptor, but save this
value separately.

Setting up Rx/Tx queue sets up both queues, release_queue close the
tap file but update file descriptor only for that queue.

This makes other queue's file descriptor invalid.

As a workaround, prevent release_queue callback to be called by default.

This is done by separating Rx/Tx setup functions, so that each only
setup its own queue, this prevents rte_eth_rx/tx_queue_setup() calling
release_queue before setup_queue.

Applied to dpdk-next-net/master, thanks.

(Just a reminder, defect still exists when app call
rte_eth_rx/tx_queue_setup() multiple times)
