scsi: iscsi: Fix session removal on shutdown
When the system is shutting down, iscsid is not running so we will not get a response to the ISCSI_ERR_INVALID_HOST error event. The system shutdown will then hang waiting on userspace to remove the session. This has libiscsi force the destruction of the session from the kernel when iscsi_host_remove() is called from a driver's shutdown callout. This fixes a regression added in qedi boot with commit d1f2ce77638d ("scsi: qedi: Fix host removal with running sessions") which made qedi use the common session removal function that waits on userspace instead of rolling its own kernel based removal.
