The extent_io_tree search helpers take return parameters and many callers pass just NULL, which are checked and add a conditionals to some paths. Reorganize helpers to suit what callers need and drop unnecessary parameters, open code rbtree search loops and clean up some other parameters. This could improve performance in some cases but it's mostly micro optimizations and I haven't done any measurements.
