[ovs-build] Still Failing: openvswitch/ovs#5253 (branch-2.8 - 379d7f9)

[Travis CI]

Build Update for openvswitch/ovs
-------------------------------------

Build: #5253
Status: Still Failing

Duration: 1 hour, 29 minutes, and 55 seconds
Commit: 379d7f9 (branch-2.8)
Author: Ilya Maximets
Message: dpif-netdev: Fix per packet cycles statistics.

DP_STAT_LOOKUP_HIT statistics used mistakenly for calculation
of total number of packets. This leads to completely wrong
per packet cycles statistics.

For example:

	emc hits:0
	megaflow hits:253702308
	avg. subtable lookups per hit:1.50
	miss:0
	lost:0
	avg cycles per packet: 248.32 (157498766585/634255770)

	In this case 634255770 total_packets value used for avg
	per packet calculation:

	  total_packets = 'megaflow hits' + 'megaflow hits' * 1.5

	The real value should be 524.38 (157498766585/253702308)

Fix that by summing only stats that reflect match/not match.
It's decided to make direct summing of required values instead of
disabling some stats in a loop to make calculations more clear and
avoid similar issues in the future.
