ip_set_create() and ip_set_net_init() attempt to allocate physically
contiguous memory for ip_set_list. If memory is fragmented, the
allocations could easily fail:
vzctl: page allocation failure: order:7, mode:0xc0d0
Call Trace:

Use kvcalloc() to fallback to 0-order allocations if high order
page isn't available.
