crypto: qat - add heartbeat error simulator

Browse source

Add a mechanism that allows to inject a heartbeat error for testing
purposes.
A new attribute `inject_error` is added to debugfs for each QAT device.
Upon a write on this attribute, the driver will inject an error on the
device which can then be detected by the heartbeat feature.
Errors are breaking the device functionality thus they require a
device reset in order to be recovered.

This functionality is not compiled by default, to enable it
CRYPTO_DEV_QAT_ERROR_INJECTION must be set.
