Revert "ibmvnic: Add ethtool private flag for driver-defined queue limits"

This reverts commit 8f4f29bce3c26aab88cdf23a9ff629b89211893a

When client requests channel or ring size larger than what the server
can support the server will cap the request to the supported max. So,
the client would not be able to successfully request resources that
exceed the server limit.
