I think this should use IXGBE_ERR_<blah> instead and there is another
spot where this could be used.  Instead I propose this patch
instead...

ixgbe: return IXGBE_ERR_RAR_INDEX when out of range

From: Jeff Kirsher <jeffrey.t.kirsher@...el.com>

Based on patch from Shirley Ma <xma@...ibm.com>
Return IXGBE_ERR_RAR_INDEX when RAR index is out of range, instead of
returning IXGBE_SUCCESS.
