tipc: use kfree_sensitive() for session key material
[ Upstream commit 74d9391e8849e70ded5309222d09b0ed0edbd039 ]
The rx->skey field contains a struct tipc_aead_key with GCM-AES
encryption keys used for TIPC cluster communication. Using plain
kfree() leaves this sensitive key material in freed memory pages
where it could potentially be recovered.
Switch to kfree_sensitive() to ensure the key material is zeroed
before the memory is freed.
