Many LLDs are missing sht->slave_destroy. The method is mandatory to
support device warm unplugging (echo 1 > /sys/.../delete). Without
it, libata might access released scsi device.

The PATA driver set got converted to the new error handling setup, but
the old hooks were accidentally left in place. Now, removed.

absent ports
This removes the layering violation where drivers have to fiddle
directly with EH flags. Instead we now recognize -ENOENT means "no port"
and do the handling in the core code.
This also removes an instance of a call to disable the port, and an
identical printk from each driver doing this. Even better - future rule
changes will be in one place only.

A couple of people reported long delays on probe with the newer kernels
and Nvidia PATA. This turned out to be because the Nvidia path forgot to
check the enable bits so probed empty ports.
