  Log Message:
  -----------
  mcast-snooping: Flush ports mdb when VLAN configuration changed.

If VLAN configuration(e.g. id, mode) change occurs, the IGMP
snooping-learned multicast groups from this port on the VLAN are
deleted. This avoids a MCAST_ENTRY_DEFAULT_IDLE_TIME delay before
mdb is updated again. Hardware switches (e.g. cisco) also do that.

  Log Message:
  -----------
  mcast-snooping: Avoid segfault for vswitchd.

The ports which are attached mrouters or hosts, were destroyed
by users via ovs-vsctl commands. Currently the vswitch will
segfault if users use "ovs-appctl mdb/show" to show mdb info.
This patch avoids a segfault.
