[SCSI] host state model update: reimplement scsi_host_cancel
Remove the old scsi_host_cancel function as it has not been working for
sometime do to the device list possibly being empty when it is called and
possible race issues. Add setting of SHOST_CANCEL at the state of beginning
of scsi_remove_host.
