ima: kexec: silence RCU list traversal warning
The ima_measurements list is append-only and doesn't require
rcu_read_lock() protection. However, lockdep issues a warning when
traversing RCU lists without the read lock:
security/integrity/ima/ima_kexec.c:40 RCU-list traversed in non-reader section!!
Fix this by using the variant of list_for_each_entry_rcu() with the last
argument set to true. This tells the RCU subsystem that traversing this
append-only list without the read lock is intentional and safe.
This change silences the lockdep warning while maintaining the correct
semantics for the append-only list traversal.
