Subject: [PATCH v2 0/4] module: logging and code improvements

This series of patches cleans up and refactors the kernel's module loading
code. The goal is to make the subsystem's logging clearer and its internal
logic more straightforward for developers to understand.

The patches in this series: 

- module: signing: Use pr_err for signature rejection
  Makes module signature rejection messages more visible.
- module: show why force load fails 
  Adds a reason to the error message when force loading is disabled.
- module: centralize no-versions force load check
  Refactors the code to centralize the "no versions" force load check.
- module: separate vermagic and livepatch checks
  Improves code organization by separating vermagic and livepatch checks.

Changes from v1:
A patch was dropped because it was based on a misunderstanding
of the ignore versioning flag's original intent.
