libvlr: lu_fsm: PS: don't terminate by timer to prevent cascade
To prevent a termination cascade, don't termine the FSM by the timer
callback when running as PS/SGSN.
The SGSN binds the LU FSM to the Attach/RAU FSM.
When the timeout happens, the Attach/RAU FSM will terminate the child FSMs
because the Attach/RAU FSM gets notified by tx_lu_rej().
