IntelFrameworkModulePkg GenericBdsLib: Potential read over memory boudary
This commit will resolve the issue brought by r17733.
StringBuffer1 = AllocateCopyPool (
MAX_STRING_LEN * sizeof (CHAR16),
L"Configuration changed. Reset to apply it Now."
);
The above using of AllocateCopyPool() will read contents out of the scope
of the constant string. Potential risk for the constant string allocated
at the boundary of memory region.
