Xin Long 6910e25de2 sctp: remove sctp_chunk_put from fail_mark err path in sctp_ulpevent_make_rcvmsg ... In Commit 1f45f78f8e ("sctp: allow GSO frags to access the chunk too"), it held the chunk in sctp_ulpevent_make_rcvmsg to access it safely later in recvmsg. However, it also added sctp_chunk_put in fail_mark err path, which is only triggered before holding the chunk. syzbot reported a use-after-free crash happened on this err path, where it shouldn't call sctp_chunk_put. This patch simply removes this call.
