Trond Myklebust 9ed8e8f684 NFSv4/flexfiles: Fix invalid deref in FF_LAYOUT_DEVID_NODE() ... [ Upstream commit 108bb4afd351d65826648a47f11fa3104e250d9b ] If the attempt to instantiate the mirror's layout DS pointer failed, then that pointer may hold a value of type ERR_PTR(), so we need to check that before we dereference it.
