VMX/vPMU: fix DebugCtl MSR handling

- writes with one of the vPMU-supported flags and some unsupported one
  set got accepted, leading to a VM entry failure
- writes with one of the vPMU-supported flags set but the Debug Store
  feature unavailable produced a #GP (other than other writes to this
  MSR with unsupported bits set)
