[PATCH v3 11/18] net/dpaa: fix port_handle leak in fm_prev_cleanup

[Hemant Agrawal]

From: Vanshika Shukla <vanshika.shukla at nxp.com>

In fm_prev_cleanup(), the port_handle was not closed before being
overwritten on each iteration, causing a resource leak. Add a null
check and close the existing handle before opening a new one.
