sctp: count singleton chunks in assoc user stats

Browse Source 
[ Upstream commit e3d37210df ]

Singleton chunks (INIT, HEARTBEAT PMTU probes, and SHUTDOWN-
COMPLETE) are not counted in SCTP_GET_ASOC_STATS "sas_octrlchunks"
counter available to the assoc owner.

These are all control chunks so they should be counted as such.

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

Fixes: 196d675934 ("sctp: Add support to per-association statistics via a new SCTP_GET_ASSOC_STATS call")
