From: Li Nan <linan122@xxxxxxxxxx>
On the error path of device_add_disk(), device's memalloc_noio flag was
set but not cleared. As the comment of pm_runtime_set_memalloc_noio(),
"The function should be called between device_add() and device_del()".
Clear this flag before device_del() now.
Fixes: 25e823c8c37d ("block/genhd.c: apply pm_runtime_set_memalloc_noio on block devices")
