clang warns:

fs/btrfs/delayed-inode.c:684:6: warning: variable 'total_data_size' set
but not used [-Wunused-but-set-variable]
        int total_data_size = 0, total_size = 0;
            ^
1 warning generated.

This variable's value has been unused since commit fc0d82e103c7 ("btrfs:
sink total_data parameter in setup_items_for_insert"). Eliminate it.

Fixes: fc0d82e103c7 ("btrfs: sink total_data parameter in setup_items_for_insert")
