net/txgbe: rename some extended statistics

[ upstream commit d7494d6 ]

Rename rx_oversize_errors to rx_oversize_cnt since it depends on giant
packet size limit instead of MTU, by hardware design.
Rename rx_drop_packets to rx_rdb_drop to indicate the drop location.
And add rx_dma_drop to extended statistics.

Fixes: 91fe49c ("net/txgbe: support device xstats")
