When there are no SPQ entries left in the free_pool, new entries are
allocated and are added to the unlimited list. When an entry in the pool
is available, the content is copied from the original entry, and the new
entry is sent to the device. qed_spq_post() is not aware of that, so the
additional entry is stored in the original entry as p_post_ent, which can
later be returned to the pool.
