[SCSI] sr: fix corrupt CD data after media change and delay
Reported-by: Geert Uytterhoeven <Geert.Uytterhoeven@sonycom.com>
If you delay 30s or more before mounting a CD after inserting it then
the kernel has the wrong value for the CD size.

The problem is in sr_test_unit_ready(): the function eats unit
attentions without adjusting the sdev->changed status. This means
that when the CD signals changed media via unit attention, we can
ignore it. Fix by making sr_test_unit_ready() adjust the changed
status.
