[PATCH] fix DMI onboard device discovery

Attached patch fixes invalid pointer arithmetic in DMI code to make onboard
device discovery working again.

akpm: bug has been present since dmi_find_device() was added in 2.6.14.
Affects ipmi only (I think) - the symptoms weren't described.

akpm: changed to use pointer arithmetic rather than open-coded sizeof.
