xfrm: Fix crash when the hold queue is used.
The commits "xfrm: Move dst->path into struct xfrm_dst" and "net: Create and use new helper xfrm_dst_child()." changed xfrm bundle handling under the assumption that xdst->path and dst->child are not a NULL pointer only if dst->xfrm is not a NULL pointer. That is true with one exception. If the xfrm hold queue is used to wait until a SA is installed by the key manager, we create a dummy bundle without a valid dst->xfrm pointer. The current xfrm bundle handling crashes in that case. Fix this by extending the NULL check of dst->xfrm with a test of the DST_XFRM_QUEUE flag. Fixes: 0f6c480f23f4 ("xfrm: Move dst->path into struct xfrm_dst") Fixes: b92cf4aab8e6 ("net: Create and use new helper xfrm_dst_child().")
