buffers: bring back cache occupancy improvement

The improvement was removed in 40129,
causing 5-40% regressions in AVF tests.

There is a memory-speed trade-off,
this change prefers speed over memory efficiency.

Ideally, the choice should be configurable,
but that is not easy to achieve, considering
how early is vlib_buffer_main_init called.

Type: fix
