pata_legacy: don't call ata_host_detach() after initialization failure 

ata_host_detach() detaches an attached port and shouldn't be called on
a port which hasn't been attached yet.  pata_legacy incorrectly calls
ata_host_detach() on unattached port after initialization failure
causing oops.  Fix it.
