Subject: net/mlx5: Fix error flow in CREATE_QP command
Patch-mainline: v4.15-rc5
Git-commit: dbff26e44dc3ec4de6578733b054a0114652a764
References: bsc#1046303 FATE#322944
In error flow, when DESTROY_QP command should be executed, the wrong
mailbox was set with data, not the one that is written to hardware,
Fix that.
Fixes: 09a7d9eca1a6 '{net,IB}/mlx5: QP/XRCD commands via mlx5 ifc'
