mem: get memzone from any CPU socket when hugepages are disabled

Browse Source 
When huge pages are disabled, memory is allocated for a single, undefined
CPU socket using malloc(), causing rte_memzone_reserve_aligned() to fail
most of the time.

This patch causes that memory to use SOCKET_ID_ANY instead of 0, and allow
it to be used in place of any socket ID specified by user.
