Fix USB CB/CBI storage devices with CONFIG_VMAP_STACK=y
commit 2ce9d2272b98743b911196c49e7af5841381c206 upstream.
Some code (all error handling) submits CDBs that are allocated
on the stack. This breaks with CB/CBI code that tries to create
URB directly from SCSI command buffer - which happens to be in
vmalloced memory with vmalloced kernel stacks.
Let's make copy of the command in usb_stor_CB_transport.
