RMPOPT_WORK_TIMEOUT is used by snp_rmpopt_all_physmem() (mod_delayed_work()), which is added in the next patch — I'll
move the define there so each patch is self-contained. 

It isn't periodic either: the handler doesn't re-arm itself. The work runs at setup and re-init with queue_delayed_work(), 
and then per SNP-guest teardown via mod_delayed_work() (batched by the timeout) once the later patches wire that up.

Thanks,
