sctp: remove the left unnecessary check for chunk in sctp_renege_events

Commit fb23403536ea ("sctp: remove the useless check in
sctp_renege_events") forgot to remove another check for
chunk in sctp_renege_events.

Dan found this when doing a static check.

This patch is to remove that check, and also to merge
two checks into one 'if statement'.
