KVM: VMX: Report up-to-date exit qualification to userspace

Browse Source 
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().
