[PATCH] remove timer debug field

Remove timer_list.magic and associated debugging code.

I originally added this when a spinlock was added to timer_list - this meant
that an all-zeroes timer became illegal and init_timer() was required.

That spinlock isn't even there any more, although timer.base must now be
initialised.

I'll keep this debugging code in -mm.
