NFC: hci: Change nfc_hci_send_response gate parameter to pipe
As there can be several pipes connected to the same gate, we need to know which pipe ID to use when sending an HCI response. A gate ID is not enough. Instead of changing the nfc_hci_send_response() API to something not aligned with the rest of the HCI API, we call nfc_hci_hcp_message_tx directly.
