Subject: [PATCH AUTOSEL 5.4 048/266] RDMA/mlx5: Add init2init as a modify command

From: Aharon Landau <aharonl@...lanox.com>

[ Upstream commit 819f7427bafd494ef7ca4942ec6322db20722d7b ]

Missing INIT2INIT entry in the list of modify commands caused DEVX
applications to be unable to modify_qp for this transition state. Add the
MLX5_CMD_OP_INIT2INIT_QP opcode to the list of allowed DEVX opcodes.

Fixes: e662e14d801b ("IB/mlx5: Add DEVX support for modify and query commands")
