usb: hub: use DMA-capable memory in usb_hub_configure
usb_hub_configure does a lot of control transfers to `buffer', a
stack-allocated variable. Switch it to a suitably aligned buffer
allocated with dma_alloc() instead.
The cleanup on error intentionally doesn't touch `hub'. Errors should
probably invalidate this, but that's out-of-scope for this DMA fix.
