patch ospray to fix a number of paraview crashes
Various reset conditions in paraview cause ospray to shutdown and reinit. Doing so exposes a bug in ospray where functions from a stale/unloaded library would be called.
The corresponding upstream pull request is at: https://github.com/ospray/ospray/pull/339
This is the release side MR corresponding to !618 (merged) in which I flubbed the backport string.
