True. Thanks for correcting me here.
It is't realy necessary print err message because ata_pci_device_do_resume()
already done this. So just remove braces.


 Since commit:553c4aa630af7bc885e056d0436e4eb7f238579b
 ata_pci_device_do_resume() can return error code, all callers was updated
 except this one.
