If everything is copacetic (no cracks, etc) flip the fork around and ram it into a sturdy wall (with the tire in naturally...). Repeat until the sockets in the crown are inline with the fork legs roughly halfway down... Then repeat the check for cracks/damage.

It can be bent back less crudely with a tubing bender--most large bicycle shops should have one on hand, but you need a sturdy pipe vise to hold the steerer tube to apply the pressure.

All of that done at your own risk, of course.
