btrfs: pass only eb to num_extent_pages
Almost all callers pass the start and len as 2 arguments but this is not necessary, all the information is provided by the eb. By reordering the calls to num_extent_pages, we don't need the local variables with start/len. Reviewed-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
