USB: storage: Avoid I/O errors when issuing SCSI ioctls to JMicron USB/ATA bridge

Here's the patch that implements the fix you suggested to avoid the
I/O errors that I was running into with my new USB enclosure with a
JMicron USB/ATA bridge, while issuing scsi-io USN or other such
queries used by Fedora's mkinitrd.
