Clean up XFA code which causes warnings
This is part of efforts to bring XFA to chromium_code standard. The warnings are from unreachable code, or using potentially uninitialized variables, or using assignment within a condition. This change list only contains easy to fix cases. More cleanups will follow. BUG=pdfium:29 Review-Url: https://codereview.chromium.org/1998873002
