tipc: fix RCU dereference race in tipc_aead_users_dec()
[ Upstream commit 6a65c0cb0ff20b3cbc5f1c87b37dd22cdde14a1c ]
tipc_aead_users_dec() calls rcu_dereference(aead) twice: once to store
in 'tmp' for the NULL check, and again inside the atomic_add_unless()
call.
Use the already-dereferenced 'tmp' pointer consistently, matching the
correct pattern used in tipc_aead_users_inc() and tipc_aead_users_set().
Fixes: fc1b6d6de220 ("tipc: introduce TIPC encryption & authentication")
