====================
ionic: code cleanup for heartbeat, dma error counts, sizeof, stats

These patches are a few more bits of code cleanup found in
testing and review: count all our dma error instances, make
better use of sizeof, fix a race in our device heartbeat check,
and clean up code formatting in the ethtool stats collection.
