Statd should always 'chdir' to its state directory.

s statd can be started by 'mount' which can sometimes be run by a
normal user, the current-working-directory could be anything.  In
partcular it could be in a mounted filesystem.  As 'statd' continues
running as a daemon it could keep prevent that filesystem from being
unmounted.

statd does currently 'chdir' to the state directory, but only if the
state directory is not owned by root.  This is wrong - it should check
for root after the chdir, not before.

So swap the two if statements around.
