    vzstat: Fix incorrect [in]active anon/file memory statistics
    
    Use contants from correct enums:
       NR_{ACTIVE,INACTIVE}_{ANON,FILE} -> NR_ZONE_{ACTIVE,INACTIVE}_{ANON,FILE}
    
    New enum has been introduced by the commit:
       ms commit 599d0c954f91 ("mm, vmscan: move LRU lists to node")
    
    So before the patch vzstat messed types of memory to report.

    Feature: ve: extra statistics (mm, latency)
