KVM: VMX: remove ASSERT() on vmx->pml_pg validity

Browse source 
vmx->pml_pg is allocated by vmx_create_vcpu() and is only nullified
when the vCPU is destroyed by vmx_free_vcpu().  Remove the ASSERTs
on vmx->pml_pg, there is no need to carry debug code that provides
no value to the current code base.
