block: move rescan_partitions to fs/block_dev.c
Large parts of rescan_partitions aren't about partitions, and moving it to block_dev.c will allow for some further cleanups by merging it into its only caller. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Jan Kara <jack@suse.cz> Signed-off-by: Jens Axboe <axboe@kernel.dk>
