dmi: prevent linked list corruption
Adding the same item to a given linked list more than once is guaranteed
to break and corrupt the list. This is however what we do in dmi_scan
since commit 79da4721117fcf188b4b007b775738a530f574da ("x86: fix DMI out
of memory problems").
Given that there is absolutely no interest in saving empty OEM strings
anyway, I propose the simple and efficient fix below: we discard the empty
OEM strings altogether.
