commit 698b8223631472bf982ed570b0812faa61955683 upstream.
1d2ef5901483004d74947bbf78d5146c24038fe7 caused a regression in ncpfs such that directories could no longer be removed. This was because ncp_rmdir checked to see if a dentry could be unhashed before allowing it to be removed. Since 1d2ef5901483004d74947bbf78d5146c24038fe7 introduced a change that incremented dentry->d_count causing it to always be greater than 1 unhash would always fail. Thus causing the error path in ncp_rmdir to always be taken. Removing this error path is safe as unhashing is still accomplished by calls to dput from vfs_rmdir.
