net: pse-pd: Fix out of bound for loop

Vulnerability Description

In the Linux kernel, the following vulnerability has been resolved: net: pse-pd: Fix out of bound for loop Adjust the loop limit to prevent out-of-bounds access when iterating over PI structures. The loop should not reach the index pcdev->nr_lines since we allocate exactly pcdev->nr_lines number of PI structures. This fix ensures proper bounds are maintained during iterations.
