sata_nv: fix fallout of devres conversion

As with all other drivers, sata_nv's hpriv is allocated with
devm_kzalloc() and there's no need to free it explicitly.  Kill
nv_remove_one() which incorrectly used kfree() instead of devm_kfree()
and use ata_pci_remove_one() directly.

Original fix is from Peer Chen.
