KarimAllah Ahmed b614c60278 KVM: Properly check if "page" is valid in kvm_vcpu_unmap 
The field "page" is initialized to KVM_UNMAPPED_PAGE when it is not used
(i.e. when the memory lives outside kernel control). So this check will
always end up using kunmap even for memremap regions.

Fixes: e45adf665a ("KVM: Introduce a new guest mapping API")
