net: sctp: Don't transition to PF state when transport has exhausted 'Path.Max.Retrans'.
Don't transition to the PF state on every strike after 'Path.Max.Retrans'.
Per draft-ietf-tsvwg-sctp-failover-03 Section 5.1.6:
Additional (PMR - PFMR) consecutive timeouts on a PF destination
confirm the path failure, upon which the destination transitions to the
Inactive state. As described in [RFC4960], the sender (i) SHOULD notify
ULP about this state transition, and (ii) transmit heartbeats to the
Inactive destination at a lower frequency as described in Section 8.3 of
[RFC4960].
This also prevents sending SCTP_ADDR_UNREACHABLE to the user as the state
bounces between SCTP_INACTIVE and SCTP_PF for each subsequent strike.
