singleton chunks (INIT, and less importantly SHUTDOWN and SHUTDOWN-
COMPLETE) are not counted in SCTP_GET_ASOC_STATS "sas_octrlchunks"
counter available to the assoc owner.

INIT (and the SHUTDOWN chunks) are control chunks so they should be
counted as such.

Add counting of singleton chunks so they are properly accounted for.

Please also fix it for pmtu probes a bit below. They are heartbeats
being handled specially as singletons as well.

Since a v2 is needed, please add also a suitable fixes tag - possibly:

Fixes: 196d67593439 ("sctp: Add support to per-association statistics via a new SCTP_GET_ASSOC_STATS call")

Thanks!
