This series of patches resolves several SCTP association hangs observed during
SCTP stress testing.  Observable symptoms include communications hangs with
data being held in the association reassembly and/or lobby (ordering) queues.
Close examination of reassembly/ordering queues may show either duplicated
or missing packets.

In version #2, corrected build failure in initial version of patch series
due to wrong calling sequence for sctp_ulpq_partial_delivery() being inserted
in sctp_ulpq_renege().

In version #3, adjusted patch documentation to be less repetitive.
My Acks from version 1 still apply.
