usb: dwc3: gadget: Reinitiate stream for all host NoStream behavior

Browse source

There are too many different host behaviors when it comes to NoStream
handling, and not everyone follows the USB and xHCI spec. The DWC3
driver attempts to do some guess work to interop with different hosts,
but it can't cover everything. Let's keep it simple and treat every host
the same: just retry on NoStream after a 100ms of no response delay.
Note that some hosts cannot handle frequent retries. This may affect
performance on certain defective hosts, but NoStream is a rare
occurrence and interoperability is more important.
