Andreas Rheinhardt 62dc4c2df5 avcodec/utils: Only call codec->close if init has been called
avcodec_open2() also called the AVCodec's close function if an error
happened before init had ever been called if the AVCodec has the
FF_CODEC_CAP_INIT_CLEANUP flag set. This is against the documentation of
said flag: "The codec allows calling the close function for deallocation
even if the init function returned a failure."

E.g. the SVQ3 decoder is not ready to be closed if init has never been
called.

Fixes: NULL dereference
