[linux-nfc] [neard][PATCH 13/16] ndef: silence clang -Wcast-align warning

[Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>]

Fix clang warning:

    src/ndef.c:1196:28: error: cast from 'char *' to 'gunichar2 *' (aka 'unsigned short *') increases required alignment from 1 to 2 [-Werror,-Wcast-align]
                            g_str = g_utf16_to_utf8((gunichar2 *)txt, len, NULL,
                                                    ^~~~~~~~~~~~~~~~

The case is safe as length of string is an even number.
