mm/vmstat: utilize designated initializers for the vmstat_text array

Browse Source 
The vmstat_text array defines labels for counters displayed in
/proc/vmstat.  The current definition of the array implies a specific
order of the counters in their enums, making it fragile.

To make it clear which counter the label is for, use designated
initializers.
