Subject[PATCH] block: Set memalloc_noio to false in the error path
Date
From: Zhong Jinghua <zhongjinghua@huawei.com>

In del_gendisk, memalloc_noio is set to false, so it would be better to do
the same thing in the error path.

Fixes: 83cbce957446 ("block: add error handling for device_add_disk / add_disk")
