[PATCH v5 2/5] windowscodecs: In find_decoder(), get rid of nested if by using goto, and use IWICWineDecoder_Initialize() to initialize decoders.

If we keep the nested if in find_decoder(), after code for calling IWICWineDecoder_Initialize() is added, the nested blocks will become too deep, which makes the code really hard to read. So here I use goto to get rid of them.

v5: It's a new patch in this patch set.

The end of the loop checks the interface pointers and releases them,
but it doesn't set them to NULL. This might cause us to release the
interfaces too many times. I suggest moving the declaration of
wine_decoder, decoderinfo, and unkdecoderinfo inside the loop.
