[Matt Wolenetz]

ffmpeg | branch: master | Matt Wolenetz <wolenetz at chromium.org> | Mon Mar  5 15:59:18 2018 -0800| [b59b59944693e645cdcf5e61b60f288820fe48c3] | committer: Michael Niedermayer

lavc/vorbisdec: Allow avcodec_open2 to call .close

If there is a decoder initialization failure detected in avcodec_open2
after .init is called, allow graceful decoder .close to prevent leaking
vorbis decoder allocations such as those from vorbis_parse_setup_*.

BUG=772699
