[PATCH] fix display of NBD in /proc/partitions

The recent change to /proc/partitions which prevents it from displaying
removeable media accidentally caused 128 NBD and 16 ramdisk partitions to
appear in /proc/partitions instead.

So add a specific gendisk flag which says "don't show me in /proc/partitions"
and use that.
