fix: Enable switch rename

Allow switch to be renamed

[taliesins]

@MarkusRannare not sure why you included these checks. Perhaps you can tell me how to reproduce problem. I suspect its a particular combination that is preventing a change to an attribute.

	if len(netAdapterNames) > 1 {
		return fmt.Errorf("[ERROR][hyperv] Can't update a switch with multiple net adapaters names (%v)", netAdapterNames)
	}

if ($vmSwitch.NetAdapterNames.length -gt 0) {
	$NetAdapterNames = [string]$vmSwitch.NetAdapterNames[0]
}

I ran into this problem with some attributes and I added this (is there another attribute we need here):

if ($NetAdapterNames) {
	$SetVmSwitchArgs.AllowManagementOS=$vmSwitch.AllowManagementOS
	$SetVmSwitchArgs.NetAdapterName=$NetAdapterNames
	#Updates not supported on:
	#-EnableEmbeddedTeaming $vmSwitch.EmbeddedTeamingEnabled
	#-EnableIov $vmSwitch.IovEnabled
	#-EnablePacketDirect $vmSwitch.PacketDirectEnabled
	#-MinimumBandwidthMode $minimumBandwidthMode
} else {
	$SetVmSwitchArgs.SwitchType=$switchType
	#Updates not supported on:
	#-EnableEmbeddedTeaming $vmSwitch.EmbeddedTeamingEnabled
	#-EnableIov $vmSwitch.IovEnabled
	#-EnablePacketDirect $vmSwitch.PacketDirectEnabled
	#-MinimumBandwidthMode $minimumBandwidthMode

	#not used unless interface is specified
	#-AllowManagementOS $vmSwitch.AllowManagementOS
}
