staging: erofs: rearrange vle clustertype definitions
This patch moves vle clustertype definitions to erofs_fs.h since they are part of on-disk format. It also adds compile time check for Z_EROFS_VLE_DI_CLUSTER_TYPE_BITS Signed-off-by: Gao Xiang <gaoxiang25@huawei.com> Reviewed-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
