[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. Signed-off-by: Mike Anderson <andmike@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
