ehci: don't flush cache on doorbell rings.

Commit 4be23939ab0d7019c7e59a37485b416fbbf0f073 makes ehci instantly
zap any unlinked queue heads when the guest rings the doorbell.

While hacking up uas support this turned out to be a problem. The linux

usb: Convert usb_packet_{map, unmap} to universal DMA helpers

The USB UHCI and EHCI drivers were converted some time ago to use the
pci_dma_*() helper functions. However, this conversion was not complete
because in some places both these drivers do DMA via the usb_packet_map()...

uhci: fix uhci_async_cancel_all

We update the QTAILQ in the loop, thus we must use the SAFE version
to make sure we don't touch the queue struct after freeing it.
