Vlad Yasevich 6c548e90a0 net: Resend IGMP memberships upon peer notification. ...

[ Upstream commit 37c343b4f4 ]

When we notify peers of potential changes,  it's also good to update
IGMP memberships.  For example, during VM migration, updating IGMP
memberships will redirect existing multicast streams to the VM at the
new location.
