ntfs: skip free cluster decrement when rollback fails

Browse source

When the rollback in __ntfs_cluster_free() fails, the recursive
call returns a negative errno and the subsequent
ntfs_dec_free_clusters(vol, delta) subtracts that negative value,
adding bogus clusters to the counter on an already-failing volume.

Skip the decrement when the rollback failed.
