KVM: x86: propagate exception from permission checks on the nested page fault
Currently, if a permission error happens during the translation of the final GPA to HPA, walk_addr_generic returns 0 but does not fill in walker->fault. To avoid this, add an x86_exception* argument to the translate_gpa function, and let it fill in walker->fault. The nested_page_fault field will be true, since the walk_mmu is the nested_mmu and translate_gpu instead operates on the "outer" (NPT) instance.
