Log:
RFCreateReaderHandle(): Unref the reader is the handle is already used

The function RFCreateReaderHandle() checks if a handle is already used
by calling RFReaderInfoById() to find the associated reader.

So if RFReaderInfoById() returns with success then the handle is valid
and can't be used. A new random handle must be generated.

But since RFReaderInfoById() called REF_READER() internally we must call
UNREF_READER() to decrement the reference counter.
