Drawbridge collapse bug

From a bug report, it is possible for the hero to
appear embedded in the wall after destroying the drawbridge.  This is because
The variable "lev1", which was the entity's location, was being referenced
after e_died, but e_died can change the entity's location.  So, as <Someone>
suggested, refer to the current location directly.
