misc: fix error handling in punt_replicate
If vlib_buffer_clone (...) fails due to a buffer allocation error, update
*n_dispatched with the actual number of clones, not the requested
number of clones.
Punt_replicate(...) should not set *to_next[0] = bi0. The original
buffer is enqueued separately in punt_dispatch_node(...)
Type: fix
