rtnl: restore notifications for deleted interfaces

Browse source

The commit 984ff7a3e0 is an upstream backport. In fact, it depends on
commit 395eea6ccf ("rtnetlink: delay RTM_DELLINK notification until after ndo_uninit()")
which has not been backported in 3.18.y.

Before commit 395eea6ccf, 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 984ff7a3e0.
