Update error messages to show why no interface is selected
Browse files Browse the repository at this point in the history 
When the SRIOV network node state is not properly initialized it can hit the error "no supported NIC is selected by the nicSelector" even though the NIC may be indeed be selected. This commit updates the error message to ensure that if the user is configuring a NIC that is supported, then the error is because the SRIOV network node state is not properly initialized.
