avcodec/vorbisenc: Don't free uninitialized pointers

The Vorbis encoder allocates several arrays destined to contain pointers
to separately allocated arrays; yet these arrays are allocated without
initializing them: They are uninitialized until their final values
are stored in them; so if allocating one of the earlier subarrays fails,
all of the remaining pointers to subarrays are still uninitialized.
But they are used for freeing, resulting in crashes.

Fix this by zero-initializing the arrays with subarrays.
