PR106907 has few warnings spotted from cppcheck. In that addressing duplicate
expression issue here. Here the same expression is used twice in logical
AND(&&) operation which result in same result so removing that.

Thanks! Okay for trunk. Also okay for all backports, no need to wait
if unexpected problems in trunk show up. But still, backport to 13
first, then 12, then 11, only stop when it stops applying (or there are
no open release branches left) :-)
