usb: gadget: f_fs: fix setup request handling
This patch fixes __ffs_ep0_queue_wait() function, which now returns number of bytes transferred in USB request or error code in case of failure. This is needed by ffs_ep0_read() function, when read data is copied to userspace. It also cleans up code by removing usused variable ep0req_status.
