[PATCH v2] net/cpfl: fix datapath function configuration

[Wenjun Wu <wenjun1.wu@intel.com>]

Vector datapath is not support any advanced features for now, so disable
vector path if TX checksum offload or RX scatter is enabled.

Fixes: 2f39845891e6 ("net/cpfl: add AVX512 data path for single queue model")
