btrfs: compression: export alloc/free/get/put callbacks of all algos
The indirect calls will be replaced by a switch in compression.c. (Switch is faster than indirect calls with when Spectre mitigations are enabled). Reviewed-by: Johannes Thumshirn <jthumshirn@suse.de> Reviewed-by: Nikolay Borisov <nborisov@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>
