Subject: [PATCH] net/sctp/ulpevent.c: Deinline sctp_ulpevent_set_owner, save 1616 bytes

This function compiles to 147 bytes of machine code. 13 callsites.

I'm no expert on SCTP events, but quick reading of SCTP docs tells me that
SCTP events are not happening on every packet.
They are ASSOC_CHANGE, PEER_ADDR_CHANGE, REMOTE_ERROR and such.
Does not look performance critical.
