[SCSI] fix SCSI_IOCTL_PROBE_HOST
This returns always false with new-style drivers right now. Make it return always true instead, as a host must be present if we are able to call the ioctl (without a host attached there would be no device node to call on..) Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
