usbhost: change parameters of methods

Pass (device_t, usb_target_t) to read and write, which finally allows to drop hash tables and access device right away. Then, all callbacks to complete transfer now uses usb_transfer_batch. This requires libdrv to include libusbhost, but it is not linked against it - it is there only to share definition of usb_transfer_batch_t.
