Andreas Rheinhardt bb0e3e7a7c avformat/aviobuf: Keep checksum_ptr consistent in avio_seek() ...

Otherwise it might be > buf_ptr in which case ffio_get_checksum()
could segfault (s->buf_ptr - s->checksum_ptr would be negative
which would be converted to something very big when converted
to unsigned for the update_checksum callback).

Fixes ticket #11233.
