Update this code to support CONFIG_BLK. Each USB storage device can have

Note that I accidentally tested some other patches in the wrong place
today, and found that this patch prevents my USB SD card reader from
working when attached to Jetson TK1. I get:

### ERROR ### Please RESET the board ###
(The Request Sense error happens even in the passing cases, but in those
cases the overall "usb start" operation succeeds, and then USB storage
access does actually work. I guess my reader is a little slow to
initialize or something).
The patch immediately before this one works fine.
Can you reproduce this? If not, let me know and I'll investigate further.
