[PATCH v1] net/iavf: fix error message in default initialization process

[PATCH v1] net/iavf: fix error message in default initialization process

[Wenjun Wu]

When kernel driver does not support quanta size configuration,
it will return error. We do not expect it to occur in default
initialization process.

Fixes: b14e8a57b9fe ("net/iavf: support quanta size configuration")
