block: update a few comments in uapi/linux/blkpg.h
The big top of the file comment talk about grand plans that never happened, so remove them to not confuse the readers. Also mark the devname and volname fields as ignored as they were never used by the kernel. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>

- * Partition table and disk geometry handling

- * A single ioctl with lots of subfunctions:

- * Device number stuff:
- * get_whole_disk() (given the device number of a partition,
- * find the device number of the encompassing disk)
- * get_all_partitions() (given the device number of a disk, return the
- * device numbers of all its known partitions)
- *
- * Partition stuff:
- * add_partition()
- * delete_partition()
- * test_partition_in_use() (also for test_disk_in_use)
- *
- * Geometry stuff:
- * get_geometry()
- * set_geometry()
- * get_bios_drivedata()
- *
- * For today, only the partition stuff - aeb, 990515
