Jordi Martin f45eb9ff3c io: add error check on pipe close functions to avoid error overwriting
The current implementation allows multiple calls `Close` and `CloseWithError` in every side of the pipe, as a result, the original error can be overwritten.

This CL fixes this behavior adding an error existence check on `atomicError` type
and keeping the first error still available.

Fixes #24283
