net: bcmasp: fix OF node reference leak for phy_dn

In bcmasp_interface_create(), intf->phy_dn is obtained via
of_parse_phandle() or assigned ndev_dn. of_parse_phandle() returns a
node reference with its refcount incremented, but of_node_put() was
never called on intf->phy_dn in bcmasp_interface_destroy() or the
error unwind path in bcmasp_interface_create().

Acquire a reference on ndev_dn for the fixed-link case as well so that
intf->phy_dn consistently holds a reference, and release it with
of_node_put() on teardown and error.
