[34-longterm 158/179] USB: usb-storage: unusual_devs entry for ARM V2M motherboard.

This is a commit scheduled for the next v2.6.34 longterm release.
If you see a problem with using this for longterm, please comment.

commit a871e4f5519d8c52430052e1d340dd5710eb5ad6 upstream.

Connecting the V2M to a Linux host results in a constant stream of
errors spammed to the console, all of the form

sd 1:0:0:0: ioctl_internal_command return code = 8070000
: Sense Key : 0x4 [current]
: ASC=0x0 ASCQ=0x0

The errors appear to be otherwise harmless. Add an unusual_devs entry
which eliminates all of the error messages.
