[PATCH] tty: Reset itty for other pty

From: Peter Hurley
Date: Sat Jun 15 2013 - 09:01:25 EST

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.
