* Description:
* If val is in a valid range [0,1], then set the adapter's initial
* cfg_aer_support field. It will be up to the driver's probe_one
* routine to determine whether the device's AER support can be set
* or not.
*
* Notes:
* If the value is not in range log a kernel error message, and
* choose the default value of setting AER support and return.
*
* Returns:
* zero if val saved.
* -EINVAL val out of range
