Subject: [PATCH] Revert "Use NetworkManager::DeviceStatistics instead of
 Plasma data engine"

This reverts commit 36dd019c98107cf1f1155988915841048b607c1b to make the
speed graph work again with NetworkManager 1.0 on Leap 42.
The new code depends on NM 1.4.0 or higher, and would not show any
traffic with earlier NM versions.
