net/mlx5: Fix forced completion access non initialized command entry
[ Upstream commit f3cb3ceb ] mlx5_cmd_flush() will trigger forced completions to all valid command entries. Triggered by an asynch event such as fast teardown it can happen at any stage of the command, including command initialization. It will trigger forced completion and that can lead to completion on an uninitialized command entry. Setting MLX5_CMD_ENT_STATE_PENDING_COMP only after command entry is initialized will ensure force completion is treated only if command entry is initialized.
