[OVN] Error during execution of "add_vnic_type_and_pb_capabilities_to_lsp"

[Rodolfo Alonso]

If the port binding profile is an empty string, the call in [1] will fail, returning a "JSONDecodeError" error.

Error: https://paste.opendev.org/show/b6xvSBDMtEZGqKvEEdee/

This method was introduced in [2]. The fix should be pushed only for 2023.1 (Antelope).

    [OVN] Skip ports with VNIC type direct and no port binding

    In the method ``add_vnic_type_and_pb_capabilities_to_lsp``, if the port
    binding profile is an empty string (or something that cannot be parsed
    by jsonutils), skip this port.
