[UMPNPMGR][USETUP] Use PlugPlayControlStartDevice in usetup and umpnpmgr

Instead of PlugPlayControlResetDevice, PlugPlayControlStartDevice should
    be used for a newly installed device.
    For usetup, add a device status check before starting attempt, so we're
    not touching devices which are already started.
