* Description:
* If val is in a valid range [0,255], then set the adapter's initial
* cfg_sriov_nr_virtfn field. If it's greater than the maximum, the maximum
* number shall be used instead. It will be up to the driver's probe_one
* routine to determine whether the device's SR-IOV is supported or not.
*
* Returns:
* zero if val saved.
* -EINVAL val out of range
