[PATCH v2 2/2] security: Allow RW access to pstore device

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

The whole point of pstore device is that the guest writes crash
dumps into it. But the way SELinux label is set on the
corresponding file warrants RO access only. This is due to a
copy-paste from code around: kernel/initrd/DTB/SLIC - these are
RO indeed, but pstore MUST be writable too. In a sense it's
closer to NVRAM/disks - hence set imagelagel on it.
