f4 usb: fix tracking of OUT requests with data stages

Browse Source 
This code was mistakenly tracking the IN (device-to-host)
requests with data stages.  It should have been tracking
the OUT (host-to-device) requests with data stages.

This tracking data is important now that CDC is supported.
CDC actually uses OUT requests with data stages whereas HID
does not.  This bug only triggered once CDC was enabled.
