e1000: fix occasional panic on unload
Net drivers in general have an issue where timers fired by mod_timer or work threads with schedule_work are running outside of the rtnl_lock. With no other lock protection these routines are vulnerable to races with driver unload or reset paths. The longer term solution to this might be a redesign with safer locks being taken in the driver to guarantee no reentrance, but for now a safe and effective fix is to take the rtnl_lock in these routines.
