libata: track spindown status and skip spindown_compat if possible
Our assumption that most distros issue STANDBYNOW seems wrong. The
upstream sysvinit and thus many distros including gentoo and opensuse
don't take any action for libata disks on spindown. We can skip
compat handling for these distros so that they don't need to update
anything to take advantage of kernel-side shutdown.
