Change code that depends on "p->mode" either being a valid mode or
zero to use a p->object_type comparison to "OBJ_NONE".
The object_type() function in cache.h will not return OBJ_NONE, but
these API users are implicitly relying on the memzero() that happens
in setup_traverse_info().
Since OBJ_NONE is "0" we can also rely on that being zero'd out here,
along with the rest of the structure. I think this is slightly less
clever than "mode not set", and helps to get rid of more uses of
"mode".
