Ming Lei e82fc78557 block: don't create too many partitions ... Commit a33df75c63 ("block: use an xarray for disk->part_tbl") drops the check on max supported number of partitionsr, and allows partition with bigger partition numbers to be added. However, ->bd_partno is defined as u8, so partition index of xarray table may not match with ->bd_partno. Then delete_partition() may delete one unmatched partition, and caused use-after-free.
