[PATCH] driver core: drop __must_check from driver_for_each_device

[Heiner Kallweit <hkallweit1@gmail.com>]

There are several users of driver_for_each_device where the worker
function doesn't actually have a return value. One example is
__igb_notify_dca(). This results in dead code just to make __must_check
happy. So drop this annotation.
