Consider device as clean even if SYNCHRONIZE CACHE failed.

Browse Source 
If device reservation was preempted by other initiator, our sync request
will always fail.  Without this change CAM tried to sync cache on every
following device close, including numerous GEOM tasting opens/closes,
causing lots of useless noise in logs.

While there, increase SYNCHRONIZE CACHE timeout to default value.
