ata: libahci_platform: Fix device reference leak in ahci_platform_get_resources()

Browse source

of_find_device_by_node() takes a reference on the port platform device,
which is only used to look up its port regulator and is never released,
neither on success nor on the error paths. Drop the reference with
put_device() once the regulator has been obtained, which covers both the
success and error paths.
