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.
