sortloot memory leak

Unfreed memory noticed after interrupting the fuzzer and quitting.
query_objlist() has an early return--for touching a cockatrice
corpse--that was skipping release of sortloot info (an array with
one element per object from whichever object list was being used).

Some formatting that's been sitting around for a while got mixed in
and I decided not to take that back out.
