ansible: match vpp device config to perf config
We're not using unsafe noiommu on perf testbeds and we should mirror that config in vpp device. As a side note, on arm vpp device, enabling unsafe noiommu leads to corrupted packets, so it must be disabled at least on arm vpp device. Also update arm vpp device kernel parameters to match perf testbeds. Change-Id: Id3d3e8fcf71583cc04887b4180cd20561856d902 Signed-off-by: Juraj Linkeš <juraj.linkes@pantheon.tech>
