block: remove blkdev_writepages
While the block device code should switch to implementing
->writepages instead of ->writepage eventually, the current
implementation is entirely pointless as it does the same looping over
->writepage as the generic code if no ->writepages is present.
Remove blkdev_writepages so that we can eventually unexport
generic_writepages.
