[PATCH] compress/mlx5: fix double close for context device

[PATCH] compress/mlx5: fix double close for context device

[michaelba]

From: Michael Baum <michaelba@nvidia.com>

The context of the device opens once in the common probe and closes with
its removal.

If the probe of one of the drivers fails, it releases its resources and
then the common closes the context.
But mistakenly in the compress probe, if ther isn't enough capabilities
to support compress operations, it closes the device and then common
probe closes it again.

Remove the redundent closing from compress probe.

[PATCH v2] compress/mlx5: fix double close for context device

[michaelba]

From: Michael Baum <michaelba@nvidia.com>

The context of the device opens once in the common probe and closes with
its removal.

If the probe of one of the drivers fails, it releases its resources and
then the common closes the context.
But mistakenly in the compress probe, if there isn't enough capabilities
to support compress operations, it closes the device and then common
probe closes it again.

Remove the redundant closing from compress probe.
