Hello,

This patch fixes the scenario where SMS fails to
schedule a loop and continue to the next one without
freeing data structures allocated while scheduling
the first loop.

Bootstrap and regtested on ppc64-redhat-linux.

OK for mainline?

Thanks,
Revital

Changelog:

* modulo-sched.c (sms_schedule): Avoid unfreed memory when SMS fails.
