Subject: IB/mlx5: Set uid as part of DCT commands
Patch-mainline: v4.20-rc1
Git-commit: a01a5860b209453b8c190fa304a63fada1bb9759
References: bsc#1103991 FATE#326007

Set uid as part of DCT create command so that the firmware can
manage the DCT object in a secured way.

The uid for the destroy and drain commands are set by mlx5_core.

That will enable using a DCT that was created by verbs application
to be used by the DEVX flow in case the uid is equal.
