ControlDevice: Fix removal of redirection on hub unplug

Browse source 
On unplug of USB hub that contains a redirected
device, removal of redirection is started when redirected
device PDO is still present in UsbDk device lists.

In this case UsbDk will try to send reset IOCTL to this device
and system will return STATUS_NO_SUCH_DEVICE error code.

This commit changes behavior of redirection removal
logic in a way that it will not interrupt removal
process when such an error is returned by reset.
