Since we're not only checking for metadata reservations but also if we need to throttle our delayed ref generation, reorder reserve_metadata_space() above the select_one_root() call in relocate_tree_block(). The reason we want this is because select_reloc_root() will mess with the backref cache, and if we're going to bail we want to be able to cleanly remove this node from the backref cache and come back along to regenerate it. Move it up so this is the first thing we do to make restarting cleaner. Signed-off-by:
