target: Remove legacy + unused device active I/O shutdown code
This patch removes the legacy device active I/O shutdown code that was originally called from transport_processing_thread() context during shutdown including transport_processing_shutdown() and transport_release_all_cmds(). This is due to the fact that in modern configfs control plane code by the time shutdown of an se_device instance in transport_processing_thread() is allowed to occur via: rmdir /sys/kernel/config/target/core/$HBA/$DEV all active I/O will already have been ceased while removing active configfs fabric Port/LUN symlinks. Eg: the removal of an active se_device is protected by inter-module VFS references from active Port/LUN symlinks. Two WARN_ON() checks have been added in their place before exiting transport_processing_thread() to watch out for any leaked descriptors.
