In commit fa516b66a1bf ("EVM: Allow runtime modification of the set of
verified xattrs"), the call to audit_log_start() is missing a context to
link it to an audit event. Since this event is in user context, add
the process' syscall context to the record.In addition, the orphaned keyword "locked" appears in the record. Normalize this by changing it to "xattr=(locked)".
