tty: Fix transient pty write() EIO
Commit 699390354da6c258b65bf8fa79cfd5feaede50b6
('pty: Ignore slave pty close() if never successfully opened')
introduced a bug with ptys whereby a write() in parallel with an
open() on an existing pty could mistakenly indicate an I/O error.
Only indicate an I/O error if the condition on open() actually exists.
