Ondrej Zary 5bc9e2d43f ata: pata_parport: fix memory leaks
When ida_alloc() fails, "pi" is not freed although the misleading
comment says otherwise.
Move the ida_alloc() call up so we really don't have to free "pi" in
case of ida_alloc() failure.

Also move ida_free() call from pi_remove_one() to
pata_parport_dev_release(). It was dereferencing already freed dev
pointer.

Testing revealed leak even in non-failure case which was tracked down
to missing put_device() call after bus_find_device_by_name(). As a
result, pata_parport_dev_release() was never called.
