[PATCH 00/12] Refactor and harden PLPKS code

This series contains fixes, hardening changes, and general cleanup for
the PLPKS code. It addresses error handling and input validation issues,
improves the cleanup of sensitive data, and prevents the wrapping_features
sysfs attribute from being exposed when the key-wrapping interface is not
supported.
