[dpdk-dev] [PATCH] crypto/mlx5: fix driver probing error flow

[Michael Baum]

In crypto driver probing, there are two validations after context
allocation.

When one of them fails, the context structure was not freed what caused
a memory leak.

Free it.

Fixes: debb27ea3442 ("crypto/mlx5: create login object using DevX")
Fixes: e8db4413cba5 ("crypto/mlx5: add keytag configuration")
