Radim Krčmář cad1af8cfb KVM: use slowpath for cross page cached accesses 
commit ca3f0874723fad81d0c701b63ae3a17a408d5f25 upstream.

kvm_write_guest_cached() does not mark all written pages as dirty and
code comments in kvm_gfn_to_hva_cache_init() talk about NULL memslot
with cross page accesses.  Fix all the easy way.

The check is '<= 1' to have the same result for 'len = 0' cache anywhere
in the page.  (nr_pages_needed is 0 on page boundary.)

Fixes: 8f964525a1 ("KVM: Allow cross page reads and writes from cached translations.")
