Ilia.Gavrilov 059fa49202 sctp: fix a potential OOB access in sctp_sched_set_sched()
The 'sched' index value must be checked before accessing an element
of the 'sctp_sched_ops' array. Otherwise, it can lead to OOB access.

Note that it's harmless since the 'sched' parameter is checked before
calling 'sctp_sched_set_sched'.
