btrfs: use correct compare function of dirty_metadata_bytes
commit d814a49198eafa6163698bdd93961302f3a877a4 upstream.
We use customized, nodesize batch value to update dirty_metadata_bytes.
We should also use batch version of compare function or we will easily
goto fast path and get false result from percpu_counter_compare().
Fixes: e2d845211eda ("Btrfs: use percpu counter for dirty metadata count")
