952943c3ea hv: decouple IO completion polling from idle thread
IO completion polling will access vcpu and vm structs. If doing it in
idle thread, there might be some race issues between vm destroying and
idle thread. They are running on different cores.
Got suggestion from Fengwei, decouple the polling action from idle
thread and just do it in vcpu thread, then we can guarantee idle thread
in really idle status.

21aa1907fd hv: vcpuid: cpuid leaf 07h has subleaf
Two changes:

1. cpuid leaf 07h has subleaf:
According to SDM 3-194 Vol.2A, Table 3-8, cpuid leaf 07h has sub-leaves.
cpuid.07.eax reports the maximum input for sub-leaves.
Since there is no definition for subleaf > 0 in SDM, hv only supports subleaf 0.

2. In currently hv code, cpuid leaf function 14h is disabled,
CPUID.07H:EBX.INTEL_PROCESSOR_TRACE should be disabled as well.
