gpu: host1x: Fix device reference leak in host1x_device_parse_dt() error path

After device_initialize(), the embedded struct device in struct
host1x_device should be released through the device core with
put_device().

In host1x_device_add(), if host1x_device_parse_dt() fails, the current
error path frees the object directly with kfree(device). That bypasses
the normal device lifetime handling and leaks the reference held on the
embedded struct device.

The issue was identified by a static analysis tool I developed and
confirmed by manual review.

Fix this by using put_device() in the host1x_device_parse_dt() failure
path.
