ata: libata-core: Synchronize ata_port_detach() with hotplug
The call to async_synchronize_cookie() to synchronize a port removal
and hotplug probe is done in ata_host_detach() right before calling
ata_port_detach(). Move this call at the beginning of ata_port_detach()
to ensure that this operation is always synchronized with probe.
