libata: remove libata.spindown_compat
With STANDBYDOWN tracking added, libata.spindown_compat isn't necessary anymore. If userspace shutdown(8) issues STANDBYNOW, libata warns. If userspace shutdown(8) doesn't issue STANDBYNOW, libata does the right thing. Userspace can tell whether kernel supports spindown by testing whether sysfs node manage_start_stop exists as before.
