[PATCH 11/22] e1000: Fire a link even interrupt instead of a watchdog at init.

["Kok, Auke" <auke-jan.h.kok@intel.com>]

Instead of calling a watchdog event we let our interrupt handler
cascade a link event. This allows us to spot link up immediately
after _up() without racing against a new watchdog.
