wm4 dc87758775 avio: fix potential crashes when combining ffio_ensure_seekback + crc Calling ffio_ensure_seekback() if ffio_init_checksum() has been called on the same context can lead to out of bounds memory accesses and crashes. The reason is that ffio_ensure_seekback() does not update checksum_ptr after reallocating the buffer, resulting in a dangling pointer. This effectively fixes potential crashes when opening mp3 files.
