Peter Zijlstra 721066dfd4 x86/mm/cpa: Fix cpa_flush_array() TLB invalidation ...

In commit:

  a7295fd53c ("x86/mm/cpa: Use flush_tlb_kernel_range()")

I misread the CAP array code and incorrectly used
tlb_flush_kernel_range(), resulting in missing TLB flushes and
consequent failures.

Instead do a full invalidate in this case -- for now.
