Cycles: Reintroduce device-only memory handling that got lost in Cycles X merge

Somehow only a part of rBf4f8b6dde32b0438e0b97a6d8ebeb89802987127 ended up in
Cycles X, causing the issue that commit fixed, "OPTIX_ERROR_INVALID_VALUE" when the
system is out of memory, to show up again.
This adds the missing changes to fix that problem.
