ASoC: mxs: Fix error handling in mxs_sgtl5000_probe
This function only calls of_node_put() in the regular path.
And it will cause refcount leak in error paths.
For example, when codec_np is NULL, saif_np[0] and saif_np[1]
are not NULL, it will cause leaks.
of_node_put() will check if the node pointer is NULL, so we can
call it directly to release the refcount of regular pointers.
