[ Upstream commit e3d37210df5c41c51147a2d5d465de1a4d77be7a ]
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.
