  dp-packet: Reset DPDK hwol flags on init.

Reset the DPDK hwol flags in dp_packet_init_.  The new hwol bad checksum
flag is uninitialized for non-dpdk ports and this is noticed as test
failures using netdev-dummy ports, when built with the --with-dpdk
flag set. Hence, in this case, packets may be falsely marked as having a
bad checksum. The existing APIs are simplified at the same time by
making them specific to either DPDK or otherwise; they also now
manage a single field.
