Revert "ehci: don't flush cache on doorbell rings."

This reverts commit 9bc3a3a216e2689bfcdd36c3e079333bbdbf3ba0, which got
added to fix an issue where the real, underlying cause was not stopping
the ep queue on an error.

Now that the underlying cause is fixed by the "usb: Halt ep queue and...

ehci: Properly report completed but not yet processed packets to the guest

Reported packets which have completed before being cancelled as such to the

been unable to actually trigger the race which needs this code path....

ehci: check for EHCI_ASYNC_FINISHED first in ehci_free_packet

ehci: trace guest bugs

make qemu_queue_{cancel,reset} return the number of packets released,

ehci: Fix memory leak in handling of NAK-ed packets

Currently each time we try to execute a NAK-ed packet we redo
ehci_init_transfer, and usb_packet_map, re-allocing (without freeing) the
sg list every time.

This patch fixes this, it does this by introducing another async state, so...
