bug#31902: 27.0.50; new buffer /dev/null

[markusffm]

recently a formerly unknown buffer names '/dev/null' opens while opening
any elisp code file, with the contents
Process elisp-flymake-byte-compile stderr finished.
This never happened before. How to get rid of it?

I broke it with 9740768a757141a3f0bd95ed3970cbd24111e7bd, where I though
I was fixing a bug, but rather introduced one.

Fixed in 3a47f3921bdaaf7b7d80dc3be05a5f1b1f2501eb.
