USB: Allow transfer_buffer with transfer_dma Some host controller drivers may need a PIO fallback when a DMA channel is temporarily unavailable. This patch provides an address that such drivers can use for PIO in those cases, and nulls that field out when no such address is available (highmem) which should help usbmon.
