[PATCH] KVM: VMX: Report up-to-date exit qualification to userspace

[Chao Gao]

Use vmx_get_exit_qual() to read the exit qualification.

vcpu->arch.exit_qualification is cached for EPT violation only and even
for EPT violation, it is stale at this point because the up-to-date
value is cached later in handle_ept_violation().

Fixes: 70bcd708dfd1 ("KVM: vmx: expose more information for KVM_INTERNAL_ERROR_DELIVERY_EV exits")
