Unlike head (after [JDK-8290025](https://bugs.openjdk.org/browse/JDK-8290025)), JDK17u uses `set_method(NULL)` in `nmethod::make_unloaded()` (and `nmethod::make_not_entrant_or_zombie`). We shouldn't ask `can_be_allocated_in_NonNMethod_space()` in these cases. The nmethod can't be a method handle intrinsic.

LGTM
