[PATCH v2 1/3] staging: tidspbridge: fix mgr_enum_node_info

[Ionut Nicu <ionut.nicu@gmail.com>]

The current code was always returning a non-zero status value
to userspace applications when this ioctl was called.

The error code was ENODATA, which isn't actually an error,
it's always returned by dcd_enumerate_object() when it hits the
end of list.
