Subject: staging: fsl-dpaa2/eth: Refactor interrupt arming in NAPI poll
Git-commit: e30bd4f8342ff251d110ab62eadf3ea9bf37c20f
Patch-mainline: v4.15-rc1
References: fate#326530,fate#326531,fate#326535,fate#326538,fate#326539
Take into consideration the return value of napi_complete_done(),
since there might be an indication that it's not suitable to
enable driver interrupts yet.
