Ming Lei d0f0f1b4c5 block: always remove partitions from blk_drop_partitions() ... In theory, when GENHD_FL_NO_PART_SCAN is set, no partitions can be created on one disk. However, ioctl(BLKPG, BLKPG_ADD_PARTITION) doesn't check GENHD_FL_NO_PART_SCAN, so partitions still can be added even though GENHD_FL_NO_PART_SCAN is set. So far blk_drop_partitions() only removes partitions when disk_part_scan_enabled() return true. This way can make ghost partition on loop device after changing/clearing FD in case that PARTSCAN is disabled, such as partitions can be added via 'parted' on loop disk even though GENHD_FL_NO_PART_SCAN is set. Fix this issue by always removing partitions in blk_drop_partitions(), and this way is correct because the current code supposes that no partitions can be added in case of GENHD_FL_NO_PART_SCAN.
