grep: micro-optimize hit collection for AND nodes
In addition to returning if an expression matches a line, match_expr_eval() updates the expression's hit flag if the parameter collect_hits is set. It never sets collect_hits for children of AND nodes, though, so their hit flag will never be updated. Because of that we can return early if the first child didn't match, no matter if collect_hits is set or not.
