sched/vtime: Work around an unitialized variable warning
[ Upstream commit e0d648f9d883ec1efab261af158d73aa30e9dd12 ]
Work around this warning:
kernel/sched/cputime.c: In function ‘kcpustat_field’:
kernel/sched/cputime.c:1007:6: warning: ‘val’ may be used uninitialized in this function [-Wmaybe-uninitialized]
because GCC can't see that val is used only when err is 0.
