accel/habanalabs: send disable pci when compute ctx is active

Browse Source 
Fix an issue in hard reset flow in which the driver didn't send a
disable pci message if there was an active compute context.
In hard reset, disable pci message should be sent no matter if
a compute context exists or not.
