vmstat: Null the diskstats pointer

I'm not sure why, but the make check will now fail for vmstat

Running ./vmstat.test/vmstat.exp ...
FAIL: vmstat disk information (-d option)

With the _new function returning the error.
In vmstat all other structures are set to NULL before calling _new
except the diskstat ones. This has been corrected.
