KVM: selftests: vgic_init kvm selftests fixup

Browse Source 
Bring some improvements/rationalization over the first version
of the vgic_init selftests:

- ucall_init is moved in run_cpu()
- vcpu_args_set is not called as not needed
- whenever a helper is supposed to succeed, call the non "_" version
- helpers do not return -errno, instead errno is checked by the caller
- vm_gic struct is used whenever possible, as well as vm_gic_destroy
- _kvm_create_device takes an addition fd parameter
