Prevent using SyncWrapper with no reason

[vzhestkov]

What does this PR do?

Backport of https://github.com/saltstack/salt/pull/66510

It's not really clear if it was mate intentionally or just the parameter is missing by accident here.

Due to missing io_loop paramerer it's causing setting _run_io_loop_sync to True in SaltEvent object with: https://github.com/openSUSE/salt/blob/4ec5c8bdb8aecac6752c639f494b86c7f8f57ba2/salt/utils/event.py#L235-L240

And that's why is using salt.utils.asynchronous.SyncWrapper here: https://github.com/openSUSE/salt/blob/4ec5c8bdb8aecac6752c639f494b86c7f8f57ba2/salt/utils/event.py#L362-L370
