Remove unused check in heap_xlog_insert()

8e03eb9 reverted the commit 39b66a9 which allowed freezing in the heap_insert() code path but forgot to remove the corresponding check in heap_xlog_insert(). This code is extraneous but not harmful. However, cleaning it up makes it very clear that, as of now, we do not support any freezing of pages in the heap_insert() path.
