Fix two XBZRLE corruption issues
Push zero'd pages into the XBZRLE cache A page that was cached by XBZRLE, zero'd and then XBZRLE'd again was being compared against a stale cache value Don't use 'qemu_put_buffer_async' to put pages from the XBZRLE cache Since the cache might change before the data hits the wire Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Signed-off-by: Juan Quintela <quintela@redhat.com>
