KVM: x86/mmu: Replace UNMAPPED_GVA with INVALID_GPA for gva_to_gpa()
The result of gva_to_gpa() is physical address not virtual address,
it is odd that UNMAPPED_GVA macro is used as the result for physical
address. Replace UNMAPPED_GVA with INVALID_GPA and drop UNMAPPED_GVA
macro.
No functional change intended.
