USB: usb-storage: use adaptive DMA mask
This patch (as1060) makes usb-storage set the DMA alignment mask for
SCSI slaves to match the maxpacket size of the bulk-IN endpoint,
rather than always setting it to 511. For full-speed devices that
mask is too restrictive, and wireless USB devices can have maxpacket
sizes larger than 512.
