staging/lustre: obd: remove unused data structures

Browse Source 
We want to get rid of all uses of time_t, and it turns out
that obd.h contains a bunch of them that are completely unused.

This removes those structures, along with a couple of other
structures and functions in the same file that also turned
out to be unused.
