e1000e: Call e1000e_config_collision_dist() after TCTL has been set

e1000e_config_collision_dist() sets tctl, but subsequently tctl is
overwritten.  It seems to me that as things stand the call to
e1000e_config_collision_dist() has no effect and should either be
removed or moved down a little bit.  This kernel patch takes the latter
option.
