habanalabs: remove unnecessary checks
Now that the VA block free list is not updated on context close in order to optimize this flow, no need in the sanity checks of the list contents as these will fail for sure. In addition, remove the "context closing with VA in use" print during hard reset as this situation is a side effect of the failure that caused the hard reset.
