x86, cpa: remove USER permission from the very early identity mapping attribute

remove USER from the PTE/PDE attributes for the very early identity
mapping. We overwrite these mappings with KERNEL attribute later
in the boot. Just being paranoid here as there is no need for USER bit
to be set.

If this breaks something(don't know the history), then we can simply drop
this change.
