mtrr: fix UP breakage caused during switch to stop_machine
While removing custom rendezvous code and switching to stop_machine, commit 192d8857427d ("x86, mtrr: use stop_machine APIs for doing MTRR rendezvous") completely dropped mtrr setting code on !CONFIG_SMP breaking MTRR settting on UP. Fix it by removing the incorrect CONFIG_SMP.
