Summary

In order to support the change in the way drivers get the
maximal depth for wide LLQ,
max_wide_llq_depth was added to struct ena_admin_feature_llq_desc and
will hold the device's exact maximal size as reported by the device,
this way the driver doesn't have to calculate it in a hardcoded manner.
