Paul Durrant c0fcded2e6 xen-netback: only deinitialized hash if it was initialized ... A domain with a frontend that does not implement a control ring has been seen to cause a crash during domain save. This was apparently because the call to xenvif_deinit_hash() in xenvif_disconnect_ctrl() is made regardless of whether a control ring was connected, and hence xenvif_hash_init() was called. This patch brings the call to xenvif_deinit_hash() in xenvif_disconnect_ctrl() inside the if clause that checks whether the control ring event channel was connected. This is sufficient to ensure it is only called if xenvif_init_hash() was called previously.
