x86: Add NMI types for kmap_atomic, fix

I just realized this has a kmap_atomic bug in...

The below would fix it - but it's complicating this code
some more.

Alternatively I would have to introduce something like
pte_offset_map_irq() which would make the irq/nmi detection and leave
the regular code paths alone, however that would mean either duplicating
the gup_fast() pagewalk or passing down a pte function pointer, which
would only duplicate the gup_pte_range() bit, neither is really
attractive ...
