Subject: dpaa_eth: add dropped frames to percpu ethtool stats

Git-commit: 46e93e5443a7adb66d7503f3e32a0cc3bf5b4d3e
Patch-mainline: v5.5-rc1
References: bsc#1174550

Prior to this change, the frames dropped on receive or transmit
were not displayed in the ethtool statistics, leaving the dropped
frames unaccounted for.
