Overwrite cm->error->detail before freeing

Help detect use after free of the return value of
aom_codec_error_detail(). If aom_codec_error_detail() is called after
aom_codec_encode() fails, the return value may be equal to
cm->error->detail, which is freed when aom_codec_destroy() is called.

Document the lifetime of the string returned by
aom_codec_error_detail().
