nfit: acpi_nfit_ctl(): Check out_obj->type in the right place
commit 43f89877f26671c6309cd87d7364b1a3e66e71cf upstream.
In the case of ND_CMD_CALL, we should also check out_obj->type.
The patch uses out_obj->type, which is a short alias to
out_obj->package.type.
Fixes: 31eca76ba2fc ("nfit, libnvdimm: limited/whitelisted dimm command marshaling mechanism")
