- usbh enumeration: move _parse_configuration_descriptor after SET_CONFIGURATION is successful

Browse Source 
- usbh: abort all pending xfer when SET_CONFIGURATION is complete
- use tu_edpt_release in tuh_edpt_abort_xfer instead of usbh_edpt_release
- rename _xfer_complete -> _control_xfer_complete
