ima: rename IMA_ACTION_FLAGS to IMA_NONACTION_FLAGS
Simple policy rule options, such as fowner, uid, or euid, can be checked immediately, while other policy rule options, such as requiring a file signature, need to be deferred. The 'flags' field in the integrity_iint_cache struct contains the policy action', 'subaction', and non action/subaction. action: measure/measured, appraise/appraised, (collect)/collected, audit/audited subaction: appraise status for each hook (e.g. file, mmap, bprm, read, creds) non action/subaction: deferred policy rule options and state Rename the IMA_ACTION_FLAGS to IMA_NONACTION_FLAGS.
