scsi: iscsi: Add helper to remove a session from the kernel
During qedi shutdown we need to stop the iSCSI layer from sending new nops as pings and from responding to target ones and make sure there is no running connection cleanups. Commit d1f2ce77638d ("scsi: qedi: Fix host removal with running sessions") converted the driver to use the libicsi helper to drive session removal, so the above issues could be handled. The problem is that during system shutdown iscsid will not be running so when we try to remove the root session we will hang waiting for userspace to reply. Add a helper that will drive the destruction of sessions like these during system shutdown.
