btrfs: remove total_data_size variable in btrfs_batch_insert_items()

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.
