RDS/IP: RDS takes 10 seconds to plumb the second IP back

RDS netdev event handler code effectively waits
for 10 seconds when event indicates and interface
coming back up from all-interfaces-were-down condition
OR initial state for the first interface to be revived.
(It is checking for address to be plumbed, something
that is done after this wait in case where RDS active
bonding code is doing the address plumbing!)

That code is based on assumptions about delays in
plumbing interface IP address  on which were
likely present due to bugs in legacy code.

With the current code, there is no need for
such checks before failing back interfaces
when an interface is brought back up.
