rumpdisk: implement BLKRRPART
This is used by parted to reload the partition table. Since we do not
actually implement partition tables, we can just ignore it.
* rumpdisk/block-rump.c (BLKRRPART): New macro.
(rumpdisk_device_set_status): New function.
(rump_block_emulation_ops): Set device_set_status field to
rumpdisk_device_set_status.
