net: rtnl_configure_link: fix dev flags changes arg to __dev_notify_flags
This fix addresses https://bugzilla.kernel.org/show_bug.cgi?id=201071
Commit 5025f7f7d506 wrongly relied on __dev_change_flags to notify users of
dev flag changes in the case when dev->rtnl_link_state = RTNL_LINK_INITIALIZED.
Fix it by indicating flag changes explicitly to __dev_notify_flags.
Fixes: 5025f7f7d506 ("rtnetlink: add rtnl_link_state check in rtnl_configure_link")
