[PATCH resend 2/3] nfc: Send same info for both of NFC_CMD_GET_DEVICE and NFC_EVENT_DEVICE_ADDED

[OGAWA Hirofumi]

Now, NFC_EVENT_DEVICE_ADDED doesn't send NFC_ATTR_RF_MODE. But
NFC_CMD_GET_DEVICE send.

To get NFC_ATTR_RF_MODE, we have to call NFC_CMD_GET_DEVICE just for
NFC_ATTR_RF_MODE when get NFC_EVENT_DEVICE_ADDED.

This fixes those inconsistent.

[PATCH 3/3] nfc: Fix RC-S380* needs zero-length packet

[OGAWA Hirofumi]

If sent packet size is wMaxPacketSize boundary, this device doesn't
answer. To fix this, we have to send zero-length packet in usb spec.
