dpt_i2o: fix build warning

commit f50abb9b63b1d8773e1ce32115701c06416e6f91 upstream.

We were getting build warning about:
drivers/scsi/dpt_i2o.c:183:29: warning: 'dptids' defined but not used

dptids[] is only used in the MODULE_DEVICE_TABLE so when MODULE is not
defined then dptids[] becomes unused.
