xhci: drop buffering
This patch splits the xhci_xfer_data function into three.
The xhci_xfer_data function used to do does two things:
(1) copy transfer data between guest memory and a temporary buffer.
(2) report transfer results to the guest using events.
Now we three functions to handle this:
(1) xhci_xfer_map creates a scatter list for the transfer and
uses that (instead of the temporary buffer) to build a
USBPacket.
(2) xhci_xfer_unmap undoes the mapping.
(3) xhci_xfer_report sends out events.
The patch also fixes reporting of transaction errors which must be
reported unconditinally, not only in case the guest asks for it
using the ISP flag.
[ v2: fix warning ]
