sh: fix smp_store_mb for !SMP
sh variant of smp_store_mb() calls xchg() on !SMP which is stronger than
implied by both the name and the documentation.
commit 90a3ccb0be538a914e6a5c51ae919762261563ad ("sh: define __smp_xxx,
fix smp_store_mb for !SMP") was supposed to fix it but
left the bug in place.
Drop smp_store_mb, so that code in asm-generic/barrier.h
will define it correctly depending on CONFIG_SMP.
