This reverts commit 87c320e51519a83c496ab7bfb4e96c8f9c001e89. Changing the error return code in some situations turns out to be harmful in practice. In particular Michael Ellerman reports that DHCP fails on his powerpc machines, and this revert gets things working again. Johannes Berg agrees that this revert is the best course of action for now.
