[Xen-changelog] [qemu-xen-unstable] fix segfault on con_disconnect

[patchbot@xxxxxxx]

commit 72d42d2ff65106fe61b8a4004a289a1be8ec8dc4
Author: Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>
Date:   Thu Jan 20 16:34:47 2011 +0000

    fix segfault on con_disconnect
    
    The test on xendev->gnttabdev in con_disconnect is wrong: what
    differentiates the consoles is the dev number.
