block: don't call invalidate_partition from blk_drop_partitions
Given that the device must not be busy, most of the calls from invalidate_partition that are related to file system metadata are guranteed to not happen. Just open code the calls to sync_blockdev and invalidate_bdev instead. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
