Currently the driver checks for error value of different APIs during the
uninitialization sequence. It just returns from there if there is any error
observed for one of those calls. Comparatively it is better to continue the
uninitialization sequence irrespective of whether some of them are
returning error. That way, it is more closer to complete uninitialization.
