net/enic: fix filter type used for flow API

The filter type (struct filter_v2.type) should always be set to
FILTER_DPDK_1, when advanced filtering is enabled in firmware.
Otherwise, for some old firmware versions, the driver sets
it to FILTER_USNIC_IP, and attempts to install filters fail. This
behavior matches that of the now-removed flow director implementation
(enic_clsf.c).
