accel/habanalabs: add log when eq event is not received

Add error log when no eq event is received from FW,
to cover a scenario when FW is stuck for some reason.
In such case driver will not receive neither the eq error interrupt
or the eq heartbeat event, and will just initiate a reset without
indication in the dmesg about the reason.
