KVM: nVMX: Restore a preemption timer consistency check

Browse Source 
A recently added preemption timer consistency check was unintentionally
dropped when the consistency checks were being reorganized to match the
SDM's ordering.

Fixes: 461b4ba4c7 ("KVM: nVMX: Move the checks for VM-Execution Control Fields to a separate helper function")
