radix-tree,shmem: introduce radix_tree_iter_next() shmem likes to occasionally drop the lock, schedule, then reacqire the lock and continue with the iteration from the last place it left off. This is currently done with a pretty ugly goto. Introduce radix_tree_iter_next() and use it throughout shmem.c.
