Bluetooth LE service data is trunctated at zero value

It seems that there is a small mistake in WinRT implementation:

const QByteArray bufferData;
bufferData + 16 <--

QByteArray doesn't have +int operator. I might be wrong but perhaps it falls back to "inline operator const char () const;" or "[]" or something. Anyway, it seems to end in char*, because array is terminated if service data contains zero byte.

I will submit a patch.
