TROVE-2017-004: Fix assertion failure in relay_send_end_cell_from_edge_
This fixes an assertion failure in relay_send_end_cell_from_edge_() when an origin circuit and a cpath_layer = NULL were passed. A service rendezvous circuit could do such a thing when a malformed BEGIN cell is received but shouldn't in the first place because the service needs to send an END cell on the circuit for which it can not do without a cpath_layer. Fixes #22493 Reported-by: Roger Dingledine <arma@torproject.org> Signed-off-by: David Goulet <dgoulet@torproject.org>
