stream: ensure writable.destroy() emits error once

Rodrigo Muino Tomonari requested to merge github/fork/lpinca/gh-26015 into master

Prevent the 'error' event from being emitted multiple times if writable.destroy() is called with an error before the _destroy() callback is called.

Emit the first error, discard all others.
