[PATCH v1 4/6] media: imx: imx7-media-csi: Drop unneeded src_sd check

[Laurent Pinchart <laurent.pinchart@ideasonboard.com>]

The .s_stream() and .link_validate() operations can't be called with a
NULL src_sd, as subdev nodes are not registered before the async
notifier completes. Remove the unneeded checks.
