habanalabs: extend process wait timeout in device fine

Processes that use our device are likely to use at the same time other
devices such as remote storage.

In case our device is removed and a user process is still using the
device, we need to kill the user process. However, if that process
has a thread waiting for i/o to complete on remote storage, for example,
the process won't terminate.

Let's give it enough time to terminate before giving up.
