From: Pawel Laszczak <pawell@cadence.com>

commit 99ea221f2e2f2743314e348b25c1e2574b467528 upstream.

Patch fixes incorrect status for control request.
Without this fix all usb_request objects were returned to upper drivers
with usb_reqest->status field set to -EINPROGRESS.

Fixes: 3d82904559f4 ("usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver")
