The previous commit introduced redirectable gnttab operations fairly much like-for-like, with the exception of the extra arguments to the ->open() call which were always NULL/0 anyway. This *changes* the arguments to the ->unmap() operation to include the original ref# that was mapped. Under real Xen it isn't necessary; all we need to do from QEMU is munmap(), then the kernel will release the grant, and Xen does the tracking/refcounting for the guest. When we have emulated grant tables though, we need to do all that for ourselves. So let's have the back ends keep track of what they mapped and pass it in to the ->unmap() method for us.
