[PATCH net] Revert "rtnetlink: check DO_SETLINK_NOTIFY correctly in do_setlink"

[Nicolas Dichtel]

This reverts commit 64ff90cc2e6f42596d7a0c37e41dc95292bb63b1.

The initial test was right. The goal is to advertised any modifications of
any setting of a link. The test ensures that the user won't lose an update.
