ipv4/fib: don't warn when primary address is missing if in_dev is dead
[ Upstream commit 391a20333b8393ef2e13014e6e59d192c5594471 ] After commit fbd40ea0180a ("ipv4: Don't do expensive useless work during inetdev destroy.") when deleting an interface, fib_del_ifaddr() can be executed without any primary address present on the dead interface. The above is safe, but triggers some "bug: prim == NULL" warnings. This commit avoids warning if the in_dev is dead Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.
