tools/memory-model/Documentation: Fix typo, smb->smp

The tools/memory-model/Documentation/explanation.txt file says
"For each other CPU C', smb_wmb() forces all po-earlier stores"
This commit therefore replaces the "smb_wmb()" with "smp_wmb()".

 Second, some types of fence affect the way the memory subsystem
