block: switch ->getgeo() to struct gendisk

Browse Source 
Instances are happier that way and it makes more sense anyway -
the only part of the result that is related to partition we are given
is the start sector, and that has been filled in by the caller.

Everything else is a function of the disk.  Only one instance
(DASD) is ever looking at anything other than bdev->bd_disk and
that one is trivial to adjust.
