gtp: Add net GTP cause values and a function to check for success
According to the spec the upf/pgw can accept a modified pdp context from
the request e.g. if an ipv4/6 context was requested, but only ipv4 is
availiable. Introduce a function that checks all cause values that are
considered successful.
