windows: Update isochronous OUT packet actual length

On Windows, unlike other platforms, the isochronous packet actual_length
value is not set on completion of OUT transfers. However, our API
requires the user to check this value for isochronous transfers instead
of the transfer actual_length, if the transferred length is of interest.

The usbd Length field is not used for isochronous OUT transfers:
https://docs.microsoft.com/en-us/windows-hardware/drivers/ddi/usb/ns-usb-_usbd_iso_packet_descriptor

To make it consistent with other platforms, just return the requested
length.

Fixes #1105
Closes #1107
