USB: error messages on DWC3 gadget endpoint dequeue

[João Paulo Silva Gonçalves]

Hi Marek,

I was testing fastboot image download over usb for imx8mp (from usb
recovery patch of verdin-imx8mp) and i am having error messages on
endpoint request dequeue function of DWC3 gadget controller. However,
download is working fine, so this message may not be an error. They are
happening because fastboot tx before sending a new usb request dequeue
the same request, maybe to be sure it does not send it twice. Can I
just ignore these messages? Maybe change its log level to dbg instead
of error? What do you think? The messages I am seeing are below and are
the ones with "... was not queued to ep1in-bulk".
