block: Set memalloc_noio to false on device_add_disk() error path

mainline inclusion
from mainline-v6.7-rc1
commit 5fa3d1a00c2d4ba14f1300371ad39d5456e890d7
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8SCHN

--------------------------------------

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.
