[ospfd] Do not use stale Network/Router LSAs

Browse Source 
Should a self originated Network/Router LSA with higher
LS seq. nr. be received we should flood and install it in
the LSDB but we cannot use it for our internal calculations
as it is stale.
Reorginate an new LSA to replace the stale one as soon
as possible.
