btrfs: reuse roots ulist on each leaf iteration for iterate_extent_inodes()
At iterate_extent_inodes() we collect a ulist of leaves for a given extent with a call to btrfs_find_all_leafs() and then we enter a loop where we iterate over all the collected leaves. Each iteration of that loop does a call to btrfs_find_all_roots_safe(), to determine all roots from which a leaf is accessible, and that results in allocating and releasing a ulist to store the root IDs. Instead of allocating and releasing the roots ulist on every iteration, allocate a ulist before entering the loop and keep using it on each iteration, reinitializing the ulist at the end of each iteration.
