[PATCH 1/2] net: thunder_bgx: fix fwnode leak in bgx_init_of_phy()

If a child returned by device_for_each_child_node() is not backed by
a device_node, to_of_node() returns NULL and the loop is aborted with
a bare break, without releasing the reference on the current fwnode
that device_for_each_child_node() took. Call fwnode_handle_put()
before breaking out of the loop, mirroring the existing of_node_put()
call a few lines below for the "lmac == bgx->max_lmac" exit path.
