accel/ivpu: Trigger recovery on TDR with OS scheduling

With OS scheduling mode the driver cannot determine which context
caused the timeout, so context abort cannot be used. Instead of
queuing context_abort_work, directly trigger full device recovery
when a job timeout (TDR) occurs in OS scheduling mode.
