ide: add ide_host_free() helper (take 2)
* Add ide_host_free() helper and convert ide_host_remove() to use it.
* Fix handling of ide_host_register() failure in ide_host_add(),
icside.c, ide-generic.c, falconide.c and sgiioc4.c.
While at it:
* Fix handling of ide_host_alloc_all() failure in ide-generic.c.
* Fix handling of ide_host_alloc() failure in falconide.c
(also return the correct error value if no device is found).
v2:
* falconide build fix. (From Stephen Rothwell)
