[ Upstream commit 5fa3d1a00c2d4ba14f1300371ad39d5456e890d7 ]

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.
