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.

Type: fix
