net: atm: Convert timers to use timer_setup()
In preparation for unconditionally passing the struct timer_list pointer to all timer callbacks, switch to using the new timer_setup() and from_timer() to pass the timer pointer explicitly. Also drops a redundant initialization that is already set up by DEFINE_TIMER. Cc: "David S.
