Subject: [PATCH] ibmvnic: Fix TX completion error handling
References: bsc#1184114 ltc#192237 bsc#1179243 ltc#189290
Patch-mainline: v5.10-rc7
Git-commit: ba246c175116e2e8fa4fdfa5f8e958e086a9a818
TX completions received with an error return code are not
being processed properly. When an error code is seen, do not
proceed to the next completion before cleaning up the existing
entry's data structures.
Fixes: 032c5e82847a ("Driver for IBM System i/p VNIC protocol")
