Subject: [PATCH] nvme: fix incorrect behavior when BLKROSET is called by the
user
The offending commit breaks BLKROSET ioctl because a device
revalidation will blindly override BLKROSET setting. Hence,
we remove the disk rw setting in case NVME_NS_ATTR_RO is cleared
from by the controller.
Fixes: 1293477f4f32 ("nvme: set gendisk read only based on nsattr")
