Daniel Jurgens 734dc065fc net/mlx5: Fix race for multiple RoCE enable ...

There are two potential problems with the existing implementation.

1. Enable and disable can race after the atomic operations.
2. If a command fails the refcount is left in an inconsistent state.

Introduce a lock and perform error checking.
