kvm/i386: Set proper nested state format for SVM
Currently, the nested state format is hardcoded to VMX. This will result
in kvm_put_nested_state() returning an error because the KVM SVM support
checks for the nested state to be KVM_STATE_NESTED_FORMAT_SVM. As a
result, kvm_arch_put_registers() errors out early.
Update the setting of the format based on the virtualization feature:
VMX - KVM_STATE_NESTED_FORMAT_VMX
SVM - KVM_STATE_NESTED_FORMAT_SVM
Also, fix the code formatting while at it.
Fixes: b16c0e20c7 ("KVM: add support for AMD nested live migration")
