block: remove blkdev_write_begin() and blkdev_write_end()
Remove blkdev_write_begin(), blkdev_write_end(), and their entries in
def_blk_aops. These have been unreachable since commit 487c607df790
("block: use iomap for writes to block devices") switched block device
buffered writes from generic_perform_write() to
iomap_file_buffered_write(), which bypasses aops->write_begin/end.
