KVM x86 fixes for 6.4

 - Fix a memslot lookup bug in the NX recovery thread that could
   theoretically let userspace bypass the NX hugepage mitigation

 - Fix a s/BLOCKING/PENDING bug in SVM's vNMI support

 - Account exit stats for fastpath VM-Exits that never leave the super
   tight run-loop

 - Fix an out-of-bounds bug in the optimized APIC map code, and add a
   regression test for the race.
