net: ti: icssg-prueth: Add missing icss_iep_put to error path

[ Upstream commit e409d7346648c9acff84c3cc8d291767ee2d5326 ]

Analogously to prueth_remove, just also taking care for NULL'ing the
iep pointers.

Fixes: 186734c15886 ("net: ti: icssg-prueth: add packet timestamping and ptp support")
Fixes: 443a2367ba3c ("net: ti: icssg-prueth: am65x SR2.0 add 10M full duplex support")
