ixgbe: Convert IXGBE_DESC_UNUSED from macro to static inline function
This change is a minor cleanup that converts the IXGBE_DESC_UNUSED macro into a static inline function just for the case of the code being a bit cleaner. Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
