msm: mink: Avoid handling output params if TZ op returns an err

Invoke operation is processed at couple of places in trusted env;
in TZ kernel and/or in TZ apps. If TZ kernel returns an error,
SMCInvoke driver does not process output params and returns
appropriate err to userspace. However, if error is returned from
trusted apps, SMCInvoke still processes output params and returns error
to userspace. Now, SMCInvoke driver will not process output params if
trusted app returns an error. Userspace is also expected to follow the
same rule.
