[PATCH] I2O: Bugfixes



- Removed some kmalloc's with __GFP_ZERO and replace it with memset()
  because it didn't work properly.

- Fixed returned message frame in i2o_cfg_passthru() which caused raidutils
  to display wrong error message in case a disk was missing.

- Fixed size of printk() in i2o_scsi.c.

- Fixed get_device() and put_device() in probing of the I2O controller.
