bgpd: Treat PMSI tunnel attribute as withdrawn if malformed
https://datatracker.ietf.org/doc/html/rfc6514#page-10 states:
A router that supports the PMSI Tunnel attribute considers this
attribute to be malformed if either (a) it contains an undefined
tunnel type in the Tunnel Type field of the attribute, or (b) the
router cannot parse the Tunnel Identifier field of the attribute as a
tunnel identifier of the tunnel types specified in the Tunnel Type
field of the attribute.
When a router that receives a BGP Update that contains the PMSI
Tunnel attribute with its Partial bit set determines that the
attribute is malformed, the router SHOULD treat this Update as though
all the routes contained in this Update had been withdrawn.
