Subject: [dpdk-dev] [PATCH v1] net/iavf: fix hash default set

Different device has different hash capability, it should not be expected that all hash set would be successful to set into all devices by default. So remove the return checking when hash default set. And remove gtpu hash default set, iavf only enable hash for general protocols.

Fixes: c94366cfc641 ("net/iavf: add GTPU in default hash")
