Clarify _corrupt_square.

_corrupt_square is not called on stairs/branch entries/portals, so
preserve_feat has nothing to do with them. The code has not changed, the
comment was just wrong. Also rename preserve_feat to preserve_features to match
the argument in dungeon_terrain_changed.

(cherry picked from commit 93aaa8e3e6a3dcf2c26b88dc92d4214889e78157)
