Btrfs: remove negative dentry when deleting subvolumne
The use of btrfs_dentry_delete is removing dentries from the dcache when deleting subvolumne. btrfs_dentry_delete ignores negative dentries. This is incorrect since if we don't remove the negative dentry, its parent dentry can't be removed. Signed-off-by: Yan Zheng <zheng.yan@oracle.com> Signed-off-by: Chris Mason <chris.mason@oracle.com>
