[PATCH 2/2] habanalabs: use get_task_pid() to take PID

From: Oded Gabbay
Date: Thu Apr 14 2022 - 08:57:56 EST


From: Dani Liberman <dliberman@xxxxxxxxx>

find_get_pid() isn't good in case the user process was run inside
docker.

As a result, we didn't had the PID and we couldn't kill the user
process in case the device got stuck and we needed to reset the
device.
