btrfs: compression: remove dead comments in btrfs_compress_heuristic()
Since commit a440d48c7f93 ("Btrfs: heuristic: implement sampling
logic"), btrfs_compress_heuristic() is no longer a simple "return true",
but more complex to determine if we should compress.
Thus the comment is dead and can be confusing, just remove it.
