btrfs: change return type of cache_save_setup to void

Browse source

None of the callers of `cache_save_setup` care about the return type as
the space cache is purely and optimization.
Also the free space cache is a deprecated feature that is being phased
out.

Change the return type of `cache_save_setup` to void to reflect this.
