usb, dfu gadget: switch to dfu mode in dfu_bind
- set in to_dfu_mode() f_dfu->dfu_state = DFU_STATE_dfuIDLE as after every to_dfu_mode call this is done, so move this into to_dfu_mode - switch in dfu_bind() into dfu mode: This fixes wrong "dfu-util -l" output, when calling "dfu-util -l" after a board reset, without doing a download before.
