wm4 e2e835f017 avformat/tta: fix crash with corrupted files ...

av_add_index_entry() can fail, for example because the parameters are
invalid, or because memory allocation fails. Check this; it can actually
happen with corrupted files.

The second hunk is just for robustness. Just in case functions like
ff_reduce_index() remove entries. (Not sure if this can actually
happen.)

Fixes ticket #4294.
