This function can be used to return buffers back to pool without going
through vlib_buffer_free. Buffer metadata must not be modified in any
way before buffers are returned.
@param vm - (vlib_main_t *) vlib main data structure pointer
@param buffers - (u32 * ) buffer index array
@param n_buffers - (u32) number of buffers to free
@param buffer_pool_index - (u8) buffer pool index
