block: fix partition info printouts
Recent block_class iteration updates 5c6f35c5..27f3025 broke partition info printouts. * printk_all_partitions(): Partition print out stops when it meets a partition hole. Partition printing inner loop should continue instead of exiting on empty partition slot. * /proc/partitions and /proc/diskstats: If all information can't be read in single read(), the information is truncated. This is because find_start() doesn't actually update the counter containing the initial seek. It runs to the end and ends up always reporting EOF on the second read. This patch fixes both problems.
