block: fix partition info printouts

Browse source

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.
