dpdk: fix wrong tx ring size calculations
At many places code was using constant ring size od 4096
which was defined in macro DPDK_TX_RING_SIZE.
As we support differnet ring size and default value s now
1024, we need to remove DPDK_TX_RING_SIZE and use
value stored in device structure.
For that reason dpdk_device_t.nb_tx_desc is moved to
first cacheline.
