Fixes Hyper-V Inspector network metrics values

The Hyper-V inspector is currently returning the wrong metric values. The
current values are the aggregated ones, which is not correct in scenarios
in which instances have more than one nic.
Furthermore, values were taken from the
Msvm_EthernetPortAllocationSettingData, instead of
Msvm_EthernetSwitchPortAclSettingData.
