PATCH 1/1 sctp: Process OOTB ASCONF Chunk at CLOSED state
RFC5061 said that If the received ASCONF Chunk is not associated with any association, the Chunk should be treated as OOTB. So, process this OOTB chunk according to section 8.4 of RFC4960.
Quote from RFC5061:
5.2. Upon Reception of an ASCONF Chunk
D3) If neither D1, D2, nor D2-ext locates the association, treat the
chunk as an Out Of The Blue packet as defined in [RFC4960].
