[SCSI] iscsi bugfixes: fix oops when iser is flushing io
When we enter recovery and flush the running commands we cannot freee the connection before flushing the commands. Some commands may have a reference to the connection that needs to be released before. iscsi_stop was forcing the term and suspend too early and was causing a oops in iser, so this patch removes those callbacks all together and allows the LLD to handle that detail.
