description:
vmstat: unexport file-scope variable numdisks

There is no need to make this variable externally visible.  There are
several more variables in this file that could be unexported, leave
these for someone who knows whether vmstat.c is used by other parts of
the tree as well.

No functional change, OK mrg.
