KVM: nSVM: Replace kzalloc() + copy_from_user() with memdup_user()
Replace kzalloc() followed by copy_from_user() with memdup_user() to
improve and simplify svm_set_nested_state().
Return early if an error occurs instead of trying to allocate memory for
'save' when memory allocation for 'ctl' already failed.
