Subject: [PATCH V2 3/7] net/mlx4_en: fix sparse warning on a cast which truncates
 bits from constant value

From: Or Gerlitz <ogerlitz@...lanox.com>

the MLX4_EN_WOL_DO_MODIFY flag which is defined through enum targets
bit 63, this triggers a "cast truncate bits from constant value
(8000000000000000 becomes 0)" warning from sparse, fix that by using
define instead of enum.
