accel/habanalabs: enable graceful reset mechanism for compute-reset

Browse source

The graceful reset mechanism is currently enabled only for reset
requests that will end up with hard-reset.
In future, reset requests due to errors in some device engines, are
going to be modified to request compute-reset, as the much longer
hard-reset is not really needed there.
To allow it, enable graceful reset also for compute-reset, and reset
after user releases the device won't be escalated to hard-reset in those
cases.
If watchdog expires and user didn't release the device, hard-reset will
be initiated in any case.
