Bug in HCD pipe alloc, should be BULK not ISO (IDFGH-5228)

[chipweinberger]

esp_err_t hcd_pipe_alloc(hcd_port_handle_t port_hdl, const hcd_pipe_config_t *pipe_config, hcd_pipe_handle_t *pipe_hdl)
{
....
    switch (type) {
        case USB_XFER_TYPE_CTRL:
            hal_type = USB_PRIV_XFER_TYPE_CTRL;
            break;
        case USB_XFER_TYPE_ISOCHRONOUS:
            hal_type = USB_PRIV_XFER_TYPE_ISOCHRONOUS;
            break;
        case USB_XFER_TYPE_BULK:
            hal_type = USB_PRIV_XFER_TYPE_ISOCHRONOUS; //BUG! Should be USB_PRIV_XFER_TYPE_BULK
            break;
        default:    //USB_XFER_TYPE_INTR
            hal_type = USB_PRIV_XFER_TYPE_INTR;
            break;
    }

See above. There is a clear copy past bug for USB_XFER_TYPE_BULK.
