Sepherosa Ziehau d7bc16443e hyperv/et: Fix STIMER0 operations.
- Make sure that STIMER0 is disabled before writting to it, since
  writing to an enabled STIMER will result in undefined behaviour.
- It is unnecessary to reconfigure STIMER0 upon each et_start().
- Make sure that MSR_HV_REF_TIME_COUNT will not return 0, since
  writing 0 to STIMER_COUNT will disable the target STIMER.
