Matt Carlson db21997379 tg3: Schedule at most one tg3_reset_task run 
It is possible for multiple threads in the tg3 driver to each attempt to
schedule a run of tg3_reset_task().  The multiple tg3_reset_task
executions could all wind up on the same queue (and execute serially) or
wind up on the queues of another processor (which could execute in
parallel).  Either scenario is not what was truly desired.

This patch adds a new flag, TG3_FLAG_RESET_TASK_PENDING, and uses it to
determine whether or not to schedule another run of tg3_reset_task().
With the new flag comes two new functions to facilitate scheduling and
descheduling of tg3_reset_task().
