x86/kvm: Don't use pv tlb/ipi/sched_yield if on 1 vCPU
[ Upstream commit ec756e40e271866f951d77c5e923d8deb6002b15 ]
Inspired by commit 3553ae5690a (x86/kvm: Don't use pvqspinlock code if
only 1 vCPU), on a VM with only 1 vCPU, there is no need to enable
pv tlb/ipi/sched_yield and we can save the memory for __pv_cpu_mask.
