server based time fires incorrectly

Description

In the following scenario, a server based timer fires too early.

Time Action

=============

0 rtems_timer_server_fire_after(timer1, 1000)
0 rtems_task_wake_after(500)

500 rtems_timer_server_fire_after(timer2, 250)

The problem is in the order of syncing the timer server
chain and inserting the new timer. The current order
results in timer2 being inserted before the chain is
adjusted for the 500 ticks which have passed. This
results in timer2 firing immediately because it fires
in 250 ticks which is less than the 500 ticks we
are adjusting.
