Vegard Storheil Eriksen e8f9d52d2f gdb_if: Fix USB flow control.
The introduction of the double buffering broke USB flow control, causing
loss of data when a new packet arrived with the previous still present in
the double buffer.

With this patch the endpoint is kept in NAK until the double buffer is empty.
