usb: Fix race if transfers are submitted by a thread. The USB pending transfer flag was cleared before calling the completion callback, to allow the callback code to call submit_xfer() again. Unfortunately this isn't safe in a multi-threaded environment, as another thread may see the endpoint is available before the callback is done executing and submit a new transfer. Rather than adding extra locking, specifically treat the transfer as still pending if checked from another thread while the callback is executing.
