hl_device_status() returns the status of an acquired device.
If a device is going down (following an rmmod cmd),
it should be marked as an unusable/malfunctioning device, and
hence should not be acquired.
However, since this was not the case so far (i.e., a device going
down would inaccurately return 'in reset' status allowing the user
to acquire the device) it introduced a bug where as part of a reset
flow, the driver could not kill processes that have not run yet, and
since those processes aren't blocked from reacquiring a device,
we get eventually a new flow of a driver attempting to kill all
processes in a list that can't be ever really empty.
