Pvrdtscp: move write_rdtscp_aux() to paravirt_ctxt_switch_to() -
Currently write_rdtscp_aux() is placed in update_vcpu_system_time(),
which is called by schedule() before context_switch(). This will break
the HVM guest TSC_AUX state because at this point, MSR hasn't beed
saved for HVM guests.So put the function in the point when a PV vcpu
is really scheduled in.
