ata: sata_highbank: fix OF node reference leak in highbank_initialize_phys()

Browse Source 
BugLink: https://bugs.launchpad.net/bugs/2102181

commit 676fe1f6f74db988191dab5df3bf256908177072 upstream.

The OF node reference obtained by of_parse_phandle_with_args() is not
released on early return. Add a of_node_put() call before returning.
