[VPP-153] Time going backward at init (After moving to Ubuntu 16.04)

[vvalderrv]

Description

So after moving to 16.04, I ended up having this ASSERT coming up at boot.

[New Thread 0x7fff9dd8d700 (LWP 1613)]

/home/ppfister/vpp-dev/build/open-vpp-mirror/build-data/../vppinfra/vppinfra/timing_wheel.c:57 (get_level_and_relative_time) assertion `dt >= w->current_time_index' fails

Thread 1 "vpp_main" received signal SIGABRT, Aborted.
