Viraj Shah 21b5fcdccb usb: musb: Balance list entry in musb_gadget_queue
musb_gadget_queue() adds the passed request to musb_ep::req_list. If the
endpoint is idle and it is the first request then it invokes
musb_queue_resume_work(). If the function returns an error then the
error is passed to the caller without any clean-up and the request
remains enqueued on the list. If the caller enqueues the request again
then the list corrupts.

Remove the request from the list on error.
