    Remove unused check in heap_xlog_insert()
    
    8e03eb92e9a reverted the commit 39b66a91bd 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.
