[media] V4L: soc-camera: protect hosts during probing from overzealous user-space If multiple clients are registered on a single camera host interface, the user-space hot-plug software can try to access the one, that probed first, before probing of the second one has completed. This can be handled by individual host drivers, but it is even better to hold back the user-space until all the probing on this host has completed. This fixes a race on ecovec with two clients registered on the CEU1 host, which otherwise triggers a BUG() in sh_mobile_ceu_remove_device().
