Add screen reader check when client try to prepare

If service engine terminates without unprepare by some purpose such as disable screen reader on TV,
some clients try to reprepare by service reset message.
In this case, prepare by service reset is not intended behavior.
Thus, this patch adds checking screen reader option code to avoid prepare by screen reader disable.
