MdeModulePkg/DebugLibReportStatusCode: Fix hang if format is too long
The previous commit 137ed15511e2045a7333e33ae7f1e873ce1961dd
* MdeModulePkg/DebugLib: Print partial when format string is too long
copies partial format string to DEBUG_INFO buffer but when parsing
the format modifier, the original format string is still used.
The patch fixes this issue.
