ACPICA: Utilities: Fix local printf issue.
The bug can be reproduced by using a format that do not have the width.prec
specified after a format that have the width.prec specified. The second
formatted output will be wrong. The root cause is acpi_ut_vsnprintf()
doesn't reset the specifiers to the default values.
This patch fixes this issue. BZ 1094. Reported by Yizhe Wang, fixed by
Lv Zheng.
Since acpi_ut_vprintf() is only enabled for specific OSPM now, this patch
doesn't affect Linux kernel.
