[Bug] No device scan when enabling it from runtime until the next devscan period

[sbengo]

Hello,

When a HMC device is configured when active = false and the user makes a reload conf or iniitialize the agent, the status of the device is set up as:

Parameter	Value
Active	false
Connected	true

When the user wants to activate the device, the following code section is reached:

pSeriesCollector/pkg/agent/devices/base.go

Lines 362 to 367 in 654cb9a

	case "enabled":
	status := val.Data.(bool)
	b.rtData.Lock()
	b.DeviceActive = status
	b.Infof("device STATUS ACTIVE [%t] ", status)
	b.rtData.Unlock()

And it tries to retrieve data on the following state:

Parameter	Value
Active	true
Connected	true

As it seems the device connected = true it doesn't scan the devices and it won't do it until the PendingLoops reaches 0

The following log shows the errors:
