MdeModulePkg: Fix comparison with wider widths.
https://codeql.github.com/codeql-query-help/cpp/cpp-comparison-with-wider-type
If the narrow type (smaller range) is compared against a wide type
(larger range), the narrow value may overflow before reaching the wide
value. This can cause unexpected behavior, such as:
Infinite loops (loop condition never becomes false).
Incorrect logic (comparison results are misleading).

MdeModulePkg: Fix missing NULL tests.
https://github.com/github/codeql/blob/codeql-cli-2.7.3/cpp/ql/src/Critical/MissingNullTest.qhelp
For items which allocate memory, or get a pointer from another
structure, it is important to validate that the pointers
are not null before they are dereferenced.
