    [NTOSKRNL][USETUP][UMPNPMGR] Pass user response data to
NtPlugPlayControl(PlugPlayControlUserResponse).
    
    - Windows requires 16 bytes of response data.
    - Add the PLUGPLAY_CONTROL_USER_RESPONSE_DATA type.
    - Usetup and Umpnpmgr must fail if NtPlugPlayControl(PlugPlayControlUserResponse) does
not return STATUS_SUCCESS.
