Kevin O'Connor fec12030a9 sam3x8e/timer: Be careful of races in timer_set_next() ...

It's possible for sched_del_timer() to be called on a timer that fires
just after sched_del_timer disables irqs but before the next timer is
scheduled.  In this case be sure to clear the irq pending status flag
after scheduling the next timer so that a delayed irq doesn't cause
the wrong timer to be run.  For the same reason, make sure to check
the irq pending status flag at the start of the timer irq.

Also, as a safety check, make sure timer_set_next() isn't called from
within the timer irq dispatch loop.
