Revert "net: core: dev_get_valid_name is now the same as dev_alloc_name_ns"

This reverts commit 87c320e515.

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.
