[CI] Fix CI Segfault

[JinkaiQiu]

Segmentation fault is going to happen if address sanitizer is turnd on

Greptile Summary

Fixes undefined behavior by zero-initializing drive_config structs in four test functions, preventing address sanitizer from detecting segfaults when free_configurator attempts to check uninitialized pointer fields.

• Changed drive_config config; to drive_config config = {0}; in test_values, test_full_line_comment, test_inline_comment, and test_problematic_inline_comment
• Ensures all pointer fields are NULL before ini_parse populates them, making the null checks in free_configurator function correctly

Confidence Score: 5/5

• This PR is safe to merge with no risk
• The change correctly addresses undefined behavior by zero-initializing structs with pointer fields. This is a best practice fix that prevents address sanitizer from catching segfaults caused by uninitialized pointers being checked in conditional statements. The fix is minimal, well-targeted, and follows C best practices.
• No files require special attention
