Subject: [PATCH v1 1/3] staging: media: ipu3: Drop superfluous check in imgu_vb2_stop_streaming()

The check for imgu_all_nodes_streaming() seems superfluous, since
imgu->streaming can only become true once imgu_all_nodes_streaming()
has been true. Hence, checking for imgu->streaming == true should
imply imgu_all_nodes_streaming(), and therefore suffice.
