[PATCH 5.1 108/122] dm ioctl: fix hang in early create error condition

From: Helen Koike commit 0f41fcf78849c902ddca564f99a8e23ccfc80333 upstream. The dm_early_create() function (which deals with "dm-mod.create=" kernel command line option) calls dm_hash_insert() who gets an extra reference to the md object. In case of failure, this reference wasn't being released
