[PATCH] power: use hugepage memory for queue list entry structure

[Huisong Li]

The queue_list_entry structure data is used in rx_callback of io path
when enable PMD Power Management. However its memory is currently from
normal heap memory. For better performance, use hugepage memory to
replace it.
