From: Colin Ian King <colin.king@canonical.com>
If there is an error on req->mr, req->mr is set to null, however the following statement sets req->mr->need_inval causing a null pointer dereference. Fix this by bailing out to label 'out' to immediately return and hence skip over the offending null pointer dereference.
