Subject: RDMA/mlx5: Fix mutex unlocking on error flow for steering anchor creation
From: Hamdan Igbaria <hamdani@xxxxxxxxxx>
commit 2fad8f06a582cd431d398a0b3f9be21d069603ab upstream.
The mutex was not unlocked on some of the error flows.
Moved the unlock location to include all the error flow scenarios.
