ping: fix buffer allocator error handling
The code sets f->n_vectors = n_to_send, but it can bail out of the loop if vlib_buffer_copy(...) returns 0. Need to fix f->n_vectors in the error return path, or we enqueue some number of 0xfefefefe buffer indices in a debug image or worse in a production image.
