crypto: qat - fix heartbeat error injection

The current implementation of the heartbeat error injection uses
adf_disable_arb_thd() to stop a specific accelerator engine thread
from processing requests. This does not reliably prevent the device
from generating responses.

Fix the error injection by disabling the device arbiter through
exit_arb() instead. This properly simulates a device failure by
stopping all arbitration, which results in missing responses for
sent requests.

Remove the now unused adf_disable_arb_thd() function and its
declaration.
