Subject: [PATCH 09/10] habanalabs: clear in_compute_reset when escalating to hard reset

From: Tomer Tayar <ttayar@...ana.ai>

If resetting device upon release while the release watchdog work is
scheduled, the compute reset is replaced with hard reset.
In this case, need to clear the in_compute_reset indication in the
device reset information structure.
