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