examples/dma: add force minimal copy size parameter
This patch adds force minimal copy size parameter
(-m/--force-min-copy-size), so when do copy by CPU or DMA, the real copy
size will be the maximum of mbuf's data_len and this parameter.
This parameter was designed to compare the performance between CPU copy
and DMA copy. User could send small packets with a high rate to drive
the performance test.

examples/dma: fix Tx drop statistics
The Tx drop statistic was designed to be collected by
rte_eth_dev_tx_buffer mechanism, but the application uses
rte_eth_tx_burst to send packets and this lead the Tx drop statistic
was not collected.
This patch removes rte_eth_dev_tx_buffer mechanism to fix the problem.
