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")
