Pull SCSI fixes from James Bottomley:
"These are the two bug fixes I mentioned in the final merge window
pull. One is a reversed logic check in the device busy tests which
can cause a nasty hang and another crash seen in the new SCSI pool
support if the use count ever goes to zero"
[ The device busy test already got merged from a patch earlier, so is
now duplicated. ]
