tg3: Eliminate timer race with reset_task
During shutdown, it is impossible to reliably disable the timer and
reset_task threads. Each thread can schedule the other, which leads to
shutdown code that chases its tail.
To fix the problem, this patch removes the ability of tg3_reset_task to
schedule a new timer thread. To support this change, tg3_timer no
longer terminates itself, but rather goes into a polling mode.
