[PATCH 5.9 50/75] dm: remove invalid sparse __acquires and __releases annotations

[Greg Kroah-Hartman]

From: Mike Snitzer <snit...@redhat.com>

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")
