Michal Suchanek fca92bb20c debugfs: lockdown: Allow reading debugfs files that are not world readable ...

[ Upstream commit 358fcf5ddb ]

When the kernel is locked down the kernel allows reading only debugfs
files with mode 444. Mode 400 is also valid but is not allowed.

Make the 444 into a mask.
