Xin Long a758aa6a77 sctp: properly validate chunk size in sctp_sf_ootb()
[ Upstream commit 0ead60804b ]

A size validation fix similar to that in Commit 50619dbf8d ("sctp: add
size validation when walking chunks") is also required in sctp_sf_ootb()
to address a crash reported by syzbot:

  BUG: KMSAN: uninit-value in sctp_sf_ootb+0x7f5/0xce0 net/sctp/sm_statefuns.c:3712
