timers: Do not IPI for deferrable timers
Deferrable timers do not prevent CPU from going idle and are not taken into
account on idle path. Sending an IPI to a remote CPU when a new first
deferrable timer was enqueued will wake up the remote CPU but nothing will
be done regarding the deferrable timers.
Drop IPI completely when a new first deferrable timer was enqueued.
