Subject: [PATCH 2/2] scripts/clang-tools: Remove core.uninitialized.Assign check

Remove this check as it leads to false positives in some cases (not all):

warning: Assigned value is garbage or undefined
[clang-analyzer-core.uninitialized.Assign]
      list_for_each_entry_safe(page, tmp_page, &pages, lru)
      ^
