Events were not processed during driver unload, hence unloading of driver doesn't complete when drives are disconnected while unloading of driver. So don't block events in ISR path, i,e., remove the flag ioc->remove_host so that events are getting processed during driver unload. Thus allowing driver unload to complete by processing drive removal events during driver unload.
