Subject: IB/cm: Pass the sgid_attr through various events
Patch-mainline: v4.19-rc1
Git-commit: 815d456ef21a132b60ce67908d289235e9bb896c
References: bsc#1103992 FATE#326009
Make the sgid_attr available along with path information to the event
consumer, this allows the consumer to keep using the same GID table entry
as the event is related to.
