Skip LSP host info update for trunk subports

Browse Source 
In ML2/OVN, the subports bindings are not updated with the host
information. This patch skips the LSP update in that case.

Currently the method ``update_lsp_host_info`` is stuck executing
``_wait_for_port_bindings_host``. During this time the subport
can be deleted or removed from the trunk. That will clash with
the newer operation that tries to remove the LSP port host info
and is the cause of the related bug.

Closes-Bug: #2085462
