commit bde3808bc8c2741ad3d804f84720409aee0c2972 upstream.

Fixes sparse warnings:
drivers/md/dm.c:508:12: warning: context imbalance in 'dm_prepare_ioctl' - wrong count at exit
drivers/md/dm.c:543:13: warning: context imbalance in 'dm_unprepare_ioctl' - wrong count at exit

Fixes: 971888c46993f ("dm: hold DM table for duration of ioctl rather than use blkdev_get")
