Ferruh Yigit 323e7b667f ethdev: make default behavior CRC strip on Rx
Removed DEV_RX_OFFLOAD_CRC_STRIP offload flag.
Without any specific Rx offload flag, default behavior by PMDs is to
strip CRC.

PMDs that support keeping CRC should advertise DEV_RX_OFFLOAD_KEEP_CRC
Rx offload capability.

Applications that require keeping CRC should check PMD capability first
and if it is supported can enable this feature by setting
DEV_RX_OFFLOAD_KEEP_CRC in Rx offload flag in rte_eth_dev_configure()
