[ruby/stringio] fix: prevent segfault in StringIO#seek with SEEK_END

2025-08-09T09:30:27+00:00

on null device
(https://github.com/ruby/stringio/pull/137)

Fixes segmentation fault when calling `seek` with `SEEK_END` on null
device StringIO created by
  `StringIO.new(nil)`.

```bash
ruby -e "require 'stringio'; StringIO.new(nil).seek(0, IO::SEEK_END)"
```

I tested with below versions.

```bash

[ruby/stringio] Do not issue warning when calling set_encoding if string is chilled

2025-05-13T03:20:09+00:00

StringIO does not warn for unchilled unfrozen string or for frozen
string, so it should not warn for chilled string.
