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.

When adapter is not found, pi->disconnect() is called without previous
pi->connect(). This results in error like this:
parport0: pata_parport tried to release parport when not owner
Add missing out_disconnect label and use it correctly.

pi->dev.id is unsigned so error checking of ida_alloc return value does
not work. Fix it.

Move PARIDE protocol modules out of drivers/block into
drivers/ata/pata_parport and update the CONFIG_ symbol names to
PATA_PARPORT.
[Damien]
The pata_parport driver file itsef is also moved together with the
protocol modules in drivers/ata/pata_parport.
