[PATCH resend 2/3] nfc: Send same info for both of NFC_CMD_GET_DEVICE and NFC_EVENT_DEVICE_ADDED
From: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp>

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.
