avformat/libsrt: fix cleanups on failed libsrt_open() and libsrt_setup()

- Call srt_epoll_release() to avoid fd leak on libsrt_setup() error.
- Call srt_cleanup() on libsrt_open() failure.
- Fix return value and method on mode parsing failure.

Based on a patch by Nicolas Sugino <nsugino@3way.com.ar>.
