[S390] qdio: prevent double qdio shutdown in case of I/O errors
Jan Glauber [Tue, 28 Oct 2008 10:10:13 +0000 (11:10 +0100)]
In case of I/O errors on a qdio subchannel qdio_shutdown may be
called twice by the qdio driver and by zfcp. Remove the
superfluous shutdown from qdio and let the upper layer driver
handle the error condition.
