usb-storage: reject probe of device one non-DMA HCDs when using highmem



usb-storage is the last user of the block layer bounce buffering now,
and only uses it for HCDs that do not support DMA on highmem configs.

Remove this support and fail the probe so that the block layer bounce
buffering can go away.
