Based on our experience with the local-protect bits, there is an
implementation out there that we know will tear down the LSP because
of an unrecognized flag in the RRO but that same implementation will
send a path-err when it doesn't recongnize the capability request bits
in the session attributes flags so soft-preempt will be disabled.
