oxnas: fix qc_prep return in sata driver after kernel 4.14.200

This fixes a regression after a kernel change in 4.14.200 [1] that
led to build failure on oxnas/ox820:

  drivers/ata/sata_oxnas.c:2238:13: error: initialization of
  'enum ata_completion_errors (*)(struct ata_queued_cmd *)'
  from incompatible pointer type
  'void (*)(struct ata_queued_cmd *)' [-Werror=incompatible-pointer-types]
    .qc_prep = sata_oxnas_qc_prep,
               ^~~~~~~~~~~~~~~~~~
  drivers/ata/sata_oxnas.c:2238:13: note:
  (near initialization for 'sata_oxnas_ops.qc_prep')

Our local driver is changed the same way as prototyped in the
kernel patch, i.e. return type is changed and AC_ERR_OK return
value is added.
