tty: Reset itty for other pty
commit 64e377dcd7d75c241d614458e9619d3445de44ef upstream.
Commit 19ffd68f816878aed456d5e87697f43bd9e3bd2b
('pty: Remove redundant itty reset') introduced a regression
whereby the other pty's linkage is not cleared on teardown.
This triggers a false positive diagnostic in testing.
Properly reset the itty linkage.
