rtnl: restore notifications for deleted interfaces
The commit 984ff7a3e060 is an upstream backport. In fact, it depends on
commit 395eea6ccf2b ("rtnetlink: delay RTM_DELLINK notification until after ndo_uninit()")
which has not been backported in 3.18.y.
Before commit 395eea6ccf2b, rollback_registered_many() uses rtmsg_ifinfo().
The call to this function is done with dev->reg_state set to
NETREG_UNREGISTERING, thus testing this reg_state in rtmsg_ifinfo() is
wrong.
This patch partially reverts commit 984ff7a3e060.
Fixes: 984ff7a3e060 ("rtnl/bond: don't send rtnl msg for unregistered iface")
