accel/habanalabs: fix wait_for_interrupt abortion flow

When the driver needs to abort waiters for interrupts, for cases
such as critical events that occur and driver need to do hard reset,
in such scenario the driver will complete the fence to wake up the
waiting thread, and will set the fence error indication.
The return value of the completion API will be greater than 0
since it will return the timeout, but as this indicates successful
completion, the driver should mark it as aborted.
