Thomas Weißschuh aa066afaaa nvmem: core: limit cell sysfs permissions to main attribute ones ...

commit 6bef98bafd upstream.

The cell sysfs attribute should not provide more access to the nvmem
data than the main attribute itself.
For example if nvme_config::root_only was set, the cell attribute
would still provide read access to everybody.

Mask out permissions not available on the main attribute.
