disable scatter/gather for ENA with DPDK 18.08

The scatter/gather rxmode flag was set for ENA when building against DPDK >= 18.08. ENA does not support this, so disable it. It looks like enabling it was a copy/paste error. Also, after offloads are adjusted based on whether "no-multi-seg" is set, those configurations are overwritten by copying port_conf_template over the port config. That should only happen for versions of DPDK older than 18.08 because 18.08 and newer make changes directly on the port config instead of making changes to the template. Make the clib_memcpy() conditional on the DPDK version being less than 18.08. After doing so, compiler errors complain about port_conf_template being declared but not used, so make it's declaration conditional.
