net/mlx5e: Prevent zero IPsec soft/hard limits

Browse Source 
Hardware triggers limit events when the packets arrive and are processed
through the device. In case zero was configured as a limit, the HW won't
be able to arm event as it happens at the end of execution pipeline.

Let's prevent such configuration.
