qcomtee_object_user_init() is a variadic function and when the function
return because there's no dispatch callback in QCOMTEE_OBJECT_TYPE_CB
case, there's no va_end to cleanup "ap" object initialized by va_start
and that can cause undefined behavior. So make sure to use va_end before
returning the error code when there's no dispatch callback.
This is reported by Coverity Scan as "Missing varargs init or cleanup".
