[PATCH AUTOSEL 5.7 142/388] s390/qdio: tear down thinint indicator after early error

From: Julian Wiedmann <jwi@linux.ibm.com>

[ Upstream commit 68a381746f20e5435206173e22d0a011ef78790e ]

qdio_establish() calls qdio_establish_thinint(), but later has an error
exit path that doesn't roll this call back. Fix it.

Fixes: 779e6e1c724d ("[S390] qdio: new qdio driver.")
