modulization: vmx on/off should not use vcpu param

Browse Source 
vmx.c should only take care host vmx operations, which should not
contain vcpu reference, so refine vmx on/off APIs, move out use
of vcpu by adding one per cpu vmcs_run pointer.

as now each pcpu only run on one vcpu, so just keep running vmcs
in per cpu vmcs_run pointer is enough.
