block: fix busy device checking in blk_drop_partitions
bd_super is only set by get_tree_bdev and mount_bdev, and thus not by other openers like btrfs or the XFS realtime and log devices, as well as block devices directly opened from user space. Check bd_openers instead. Fixes: 77032ca66f86 ("Return EBUSY from BLKRRPART for mounted whole-dev fs") Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
