[PATCH 06/11] btrfs-progs: Remove unused argument from clean_tree_block

[Nikolay Borisov <nborisov@suse.com>]

This function actually uses only the extent_buffer arg but takes 3
arguments. Furthermore, it's current interface doesn't even mirror
the kernel counterpart. Just remove the extra arguments.
