USB: whci-hcd: correctly handle sg lists longer than QTD_MAX_XFER_SIZE.

When building qTDs (sTDs) from a scatter-gather list, the length of the
qTD must be a multiple of wMaxPacketSize if the transfer continues into
another qTD.

This also fixes a link failure on configurations for 32 bit processors
with 64 bit dma_addr_t (e.g., CONFIG_HIGHMEM_64G).
