remove "all_partitions" option

We can not predict the major/minor of non-existing devices:
  $ grep . /sys/class/block/sd*/dev
  /sys/class/block/sda1/dev:259:524288
  /sys/class/block/sda2/dev:259:262144
  /sys/class/block/sda3/dev:259:786432
  /sys/class/block/sda4/dev:259:131072
  /sys/class/block/sda/dev:259:0
  /sys/class/block/sdb/dev:259:655360
  /sys/class/block/sdc/dev:259:393216

If this functionality is still needed for some broken hardware, it needs to be
solved with a tool not part of the udev package. Because such option is unreliable
and unsafe to use.
