Subject: [PATCH] block/nullb: delete unnecessary memory free
Git-commit: 060fd198a3e113047da456f15889579067e6b75f
Patch-mainline: v4.14-rc1
References: bsc#1104967,FATE#325924

Commit 2984c86(nullb: factor disk parameters) has a typo. The
nullb_device allocation/free is done outside of null_add_dev. The commit
accidentally frees the nullb_device in error code path.
