ata: libata: Assign print_id at port allocation time

While the assignment of ap->print_id could have been moved to
ata_host_alloc(), let's simply move it to ata_port_alloc().

If you allocate a port, you want to give it a unique name that can be used
for printing.

By moving the ap->print_id assignment to ata_port_alloc(), means that we
can also remove the ap->print_id assignment from ata_sas_port_alloc().

This will allow a LLD to use the ata_port_*() print functions before
ata_host_register() has been called.
