commit 5e47f198 upstream. This patch fixes an active I/O shutdown bug for fabric drivers using target_wait_for_sess_cmds(), where se_cmd descriptor shutdown would result in hung tasks waiting indefinitely for se_cmd->cmd_wait_comp to complete(). To address this bug, drop the incorrect list_del_init() usage in target_wait_for_sess_cmds() and always complete() during se_cmd target_release_cmd_kref() put, in order to let caller invoke the final fabric release callback into se_cmd->se_tfo->release_cmd() code.
