[S390] cio: use barrier() in stsch_reset.
Use barrier() in stsch_reset() instead of duplicating the stsch() inline assembly and adding "memory" to the clobberlist. Pointed out by Chuck Ebbert. Real fix would be to add a fixup section to the stsch() and extend the basic program check handler so it searches the exception tables in case of a program check.
