Subject: [PATCH 5.15 123/177] usb: cdnsp: Fix incorrect status for control request

From: Pawel Laszczak <pawell@...ence.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.
