Fix comment in CheckIndexCompatible().

Commit 5f173040 removed the parameter "heapRelation" from
CheckIndexCompatible(), but forgot to remove the mention of it
from the comment. This commit removes that unnecessary mention.

Also this commit adds the missing mention of the parameter "oldId"
in the comment.
