From: "Ewan D. Milne" <emi...@redhat.com>
If a device does not report a unit attention as expected,
clear the expecting_cc_ua flag so that we will not suppress
a future unit attention condition that is *not* expected.
INQUIRY and REPORT LUNS commands should not do this, however,
because they do not report pending unit attention conditions.
