The commit in Fixes has removed an fwnode_graph_get_endpoint_by_id() call
in mipi_csis_subdev_init().
So the reference that was taken should not be released anymore in the
error handling path of the probe and in the remove function.

Remove the now incorrect fwnode_handle_put() calls.

Fixes: 1029939b3782 ("media: v4l: async: Simplify async sub-device fwnode matching")
