media: dvb-usb: fix ununit-value in az6027_rc_query
[ Upstream commit afae4ef7d5ad913cab1316137854a36bea6268a5 ] Syzbot reported ununit-value bug in az6027_rc_query(). The problem was in missing state pointer initialization. Since this function does nothing we can simply initialize state to REMOTE_NO_KEY_PRESSED.
