Sukchan Lee 8c8b51790d amf,mme: Reject authentication after repeated synch failures
Limit authentication retries on repeated synchronization failures.

When the UE reports consecutive authentication failures with
"synchronization failure" cause, AMF and MME now track the failure
count per authentication procedure and send AUTHENTICATION REJECT
after two attempts, instead of retrying indefinitely.

The counter is reset on authentication state entry.

This aligns the behavior with 3GPP authentication procedures and
prevents infinite authentication loops caused by persistent
synchronization failures.
