firewire: move fw_device() and fw_unit() to use container_of_const()

Browse source

The driver core is changing to pass some pointers as const, so move
fw_device() and fw_unit() functions to use container_of_const() to
handle this change.

fw_device() and fw_unit() now properly keeps the const-ness of the
pointer passed into it, while as before it could be lost.

This also required turning fw_parent_device() into a macro to preserve
the const-ness of the pointer passed into it if necessary.
