Subject: [PATCH net-next] ipmr: ip6mr: Create new sockopt to clear mfc cache or vifs

Created a way to clear the multicast forwarding cache on a socket
without having to either remove the entries manually using the delete
entry socket option or destroy and recreate the multicast socket.

Using the flags MRT_FLUSH_ENTRIES and MRT_FLUSH_VIFS, all multicast
entries can be cleared, all multicast interfaces can be closed or both
can be cleared using one sockopt call.

Patch Set 2:
  - Created new flags to flush static entries or vifs
