Fix drivers/macintosh/adbhid.c stupid breakage

[Paul Mackerras <paulus@samba.org>]

Commit c7f7a569d9b4ea7c53ab6fcd1377895312d8372b ("[PATCH] Input:
convert drivers/macintosh to dynamic input_dev allocation") breaks any
machine with an ADB keyboard or mouse, which includes my G4
powerbook.  Was it given any testing at all?

The problem is that adbhid[]->input is NULL, so the kernel oopses with
a null pointer dereference as soon as I press a key.  The following
patch fixes it.
