ASoC: sdw_utils: fix device reference leak in is_sdca_endpoint_present()

The bus_find_device_by_name() function returns a device pointer with an
incremented reference count, but the original code was missing put_device()
calls in some return paths, leading to reference count leaks.

Fix this by ensuring put_device() is called before function exit after
  bus_find_device_by_name() succeeds

This follows the same pattern used elsewhere in the kernel where
bus_find_device_by_name() is properly paired with put_device().

Found via static analysis and code review.
