KVM: nSVM: inject exceptions via svm_check_nested_events
This allows exceptions injected by the emulator to be properly delivered
as vmexits. The code also becomes simpler, because we can just let all
L0-intercepted exceptions go through the usual path. In particular, our
emulation of the VMX #DB exit qualification is very much simplified,
because the vmexit injection path can use kvm_deliver_exception_payload
to update DR6.
